The Oregon Voting System: Statistical Evidence that it Works

This statistical analysis of Oregon’s voting history provides evidence that the vote-by-mail system introduced in 1998 has been a success.
http://richardcharnin.com/OregonVotingSystem.htm
Oregon’s recorded vote share closely matched the unadjusted state aggregate exit poll in the last three presidential elections. In 2000, 50.0 for Gore vs. 50.8 nationally; in 2004, 51.3 for Kerry vs. 51.1; in 2008, 56.7 for Obama vs. 58.0
In 2000, Al Gore had a 47.5-47.0% margin in Oregon, a close match to the national recorded vote (Gore 48.4-Bush 47.9). But Nader had 6% in Oregon and 3% nationwide. Allocating the excess 3% OR Nader vote, Gore would have won Oregon by approximately 50-47.5%. He had 50.8% in the unadjusted state exit poll aggregate.
In 2004, Kerry had a 51.3-47.4% margin in Oregon, compared to Bush’s 50.7-48.3% recorded national share. Kerry’s OR share was close to his 52% share in the OR pre-election poll as well as the unadjusted state exit poll aggregate (51.1-47.6%).
Bush improved on his 2000 recorded vote share not only in the battleground states, but also in solidly Democratic New York. But Oregon went against the grain and shifted from Gore to Kerry. Kerry’s overall Oregon margin was 3.7% higher than Gore’s. This was primarily due to Kerry’s 65-13% margin in returning Nader voters and hid 57-41% margin in new voters. The pre-election National, Oregon and Battleground polls, after adjusted for undecided voters, projected that Kerry would win by 51-48%. Post-election state and national exit polls indicated that he won by 4%. The True Vote model indicates that Kerry won by 53.5-45.5% (nearly 10 million votes) assuming a) equal 98% turnout of living returning Gore and Bush voters and b) the 12:22am National Exit Poll defection rates: 8% of Gore voters to Bush and 10% of Bush voters to Kerry.
In 2008, Oregon closely matched the National True Vote and the unadjusted state exit polls. He had 58.0% in the unadjusted state aggregate exit polls, exactly matching his National True Vote share. But Obama had just a 52.9% recorded national share. Obama won the Oregon recorded vote by 56.7-40.4%. He led 56-39% in the Oregon pre-election poll and had 58.4% in the post-election telephone survey. He won the Oregon True Vote Model by 56.0-42.8%.
To believe that Oregon’s mail-in/early voting system miscounted the votes, one must also believe that Bush did in fact legitimately match the other states recorded votes, i.e. the national and state exit polls that showed Kerry winning were all wrong. But what if the exit polls were correct? What if the votes were miscounted in the states that used electronic voting machines, punched cards or levers? Then one would have to conclude that Oregon’s system worked.
In 1988 VP Bush was the de-facto incumbent. Dukakis led by 55.0-42.9% in the Oregon exit poll. He won the state recorded vote 51.3-46.6%. He won the unadjusted state exit poll national aggregate by 50.0-49.0%. But Bush won the national recorded vote by 53.4-45.6%.
In 1992 Bush was the incumbent. Clinton led Bush by 49.3-25.7% in the Oregon exit poll but won the state recorded vote by just 42.5-32.5%. He led the unadjusted state exit poll national aggregate by 45.7-34.8%. He won the national recorded vote by 43.0-37.4%.
In 1996, Clinton was the incumbent. He led by 48.4-37.9% in the Oregon exit poll and won the state by nearly the same margin: 47.2-39.1%. He led the unadjusted state exit poll national aggregate by 50.2-39.8% and won the national recorded vote by nearly the same margin: 49.2-40.7%. His 54.7% two-party Oregon share exactly matched the National recorded share.
In 2000, Clinton was the incumbent. Gore won Oregon by 47.0-46.5% and led the unadjusted state exit poll national aggregate by 50.84-44.5%. He won nationally by nearly the same margin (48.4-47.9%) and had a 48.3% Battleground share. The National True Vote Model indicates that he won by 50-47%.
In 2004, Bush was the incumbent. Kerry led the Oregon pre-election poll by 50-44% and was projected to win by 53.7-45.3%. He won the state by 51.3-47.2%, a 3.6% improvement over Gore. Kerry led the state pre-election polls by 48-47% and was projected to win by 51-48%. He won the unadjusted state exit poll aggregate by 51.1-47.0% but lost to Bush by 50.7-48.3%. Kerry had a 53.3% national share in the True Vote Model – a 10 million vote margin.
In 2008, McCain was the de-facto incumbent. Obama led by 56-39% in the Oregon pre-election poll. He won Oregon by 56.7-40.4%. He had 58.4% in the post-election survey. The True Vote model indicates a 56.0-42.8% split. But he won by just 52.9-45.6% with a 9.5 million recorded vote margin. He had 58.0% in the unadjusted state aggregate exit polls and also had a 58% True Vote share. The triple match is powerful confirming evidence that the vote-by-mail system worked. Obama won the unadjusted National Exit poll (17836 respondents) by a whopping 61-37%.
The National, Oregon and Battleground pre-election projection and post-election exit poll shares closely match. This is a confirmation that Oregon is representative of the National and Battleground electorate. Therefore, we must conclude that the election was stolen in the Battleground states and that Oregon’s vote-by-mail system is virtually fraud-proof.
True Vote Methodology
The analysis tables provide a reasonable approximation of the National, Oregon and Battleground True Vote shares.
Given 2000 and 2004 votes recorded and cast, the True Vote calculation assumes:
1. Kerry and Gore had 75% of the uncounted (cast – recorded) votes
2. Annual 1.25% voter mortality (5% in the four years between elections)
3. Equal 98% turnout of returning 2000 voters in 2004.
4. Equal Gore and Bush returning voter defection rates (they cancel each other).
5. Kerry won returning Nader voters by 65-13% over Bush based on the National Exit Poll.
6. New 2004 voters is the difference between 2004 votes cast and returning 2000 voters.
7. Kerry won new voters by 59-39% nationally. His DNV share in each state is calculated as:
State DNV share = 0.59* (1+state exit poll share – 0.5197)*new voters, where .5197 is Kerry’s unadjusted state exit poll aggregate (national) share. For instance, in NY, Kerry’s share of 1347k DNV is 894k = 0.59*(1+.645-0.5197).
The simplifying assumption is that there was zero net defection of returning Gore and Bush voters (they cancelled each other). But the 12:22am National Exit Poll of 13,047 respondents indicates that 10% of Bush voters defected to Kerry and only 8% of Gore voters defected to Bush. The 2004 True Vote analysis shown below indicates that Kerry had a 53.7% national share assuming a net 2% defection as opposed to 53.3% assuming zero net defection. See the Recursive True Vote Model.
Kerry True Vote Sensitivity Analysis
Two groups of three tables display the effect of various model input assumptions on Kerry’s vote share. The margin of error is less than 1.5%.
-New Voters and returning Nader/other voters
Three tables display Kerry’s National, Oregon and Battleground True Vote shares over a 54-63% range of new voters and 61-69% of returning Nader/other voters. Kerry wins all worst case scenarios (54% of new voters and 61% of returning Nader voters).
-Returning Gore and Bush Voter Turnout
Three tables display Kerry’s National, Oregon and Battleground vote shares for 91-99% turnout of living former Gore and Bush voters. Kerry wins all worst case turnout scenarios (91% of living Gore voters and 99% of living Bush voters).
Oregon vs. New York and California
National
In 2000, Gore won the recorded vote by 48.4-47.9%. In 2004, although returning Nader voters broke heavily for Kerry by 65-13% and new voters by 59-39%, Bush won by 50.7-48.3%. That is not plausible.
Oregon
Gore won by 47.0-46.5%. With returning Nader and new voters breaking for Kerry, his recorded vote-count margin increased to 51.4-47.2%. That is plausible. Kerry led by 52.2-46.3% in the exit pollster telephone poll. That is plausible.
New York
Gore won by 60.2-35.2%. Although returning Nader and new voters broke heavily for Kerry, his recorded vote-count margin declined to 58.4-40.1%. That is not plausible. Kerry led by 64.5-34.0% in the exit poll. That is plausible.
California
Gore won by 53.4-41.6%. Although returning Nader and new voters broke heavily for Kerry, his recorded vote-count margin declined to 54.3-44.1%. That is not plausible. Kerry led by 60.1-38.6% in the exit poll. That is plausible.
Why did Kerry’s margin increase in Oregon, a battleground state, and decline in strongly Democratic California and New York?
Why was the exit poll so far off in California (11.6 WPE)? It voted 29% on DRE touch screens, 66% on optical scanners and 4% on punch cards.
Why was the exit poll so far off in New York (12.2 WPE)? It voted exclusively on lever machines.
Why were the exit polls so far off (7.5 WPE) in the Battleground states? They voted on punched cards, levers, optical scanners and DREs.
Florida and Ohio
In Florida 2000, there were approximately 185,000 spoiled punch cards (under-punched and over-punched). According to the Census, 43,000 more votes were cast than recorded. Where did the 142,000 extra votes come from? Bush won Florida by 537 votes.
In Florida 2004, approximately 238,000 more votes were recorded than cast. How many were uncounted? Bush won by 380,000 votes.
In Ohio 2004, according to the Census, 143,000 more votes were recorded than cast. Approximately 350,000 were uncounted (see Was the 2004 Election Stolen? by RFK, Jr.) How many votes were switched? Bush won by 119,000 votes.
Oregon’s Pre-Election Polls Uniquely Matched the Recorded and True Vote
Final-week state pre-election polls were virtually all Likely Voter (LV) subsets of the full Registered Voter (RV) samples. Likely Voter subsets largely exclude “new” voters: first-timers and others who did not vote in the prior election. The Democrats won ‘new voters’ by an average 14% margin (before Obama’s whopping 44%). Projections that ignore RV polls and focus solely on LV polls will inevitably underestimate the Democratic share, especially in heavy-turnout elections such as record-setting 2004 and 2008. In 2004, the LV polls understated voter turnout by 6%. Gross underestimates would be expected from political sites by displaying only LV polls and failing to allocate undecided voters.
Mainstream pollsters allocated undecided voters to Kerry by 2:1-to-4:1. Kerry’s projected national LV poll share was 1-2% lower than the projected RV share. In New York and California the pre-election poll projections were a virtual match to the recorded vote-count share but 5-6% below Kerry’s exit poll and True Vote shares. The same LV/RV mismatch occurred in 2008. Obama had 53% based on LV polls but a 57% projected share based on RV national polls after allocating undecided voters.
In Oregon, voting by mail results in high turnout and the pre-election polls are RVs by definition. Kerry led by 50-44% in the final poll. After undecided voter allocation (UVA), he was projected to win by 53-45%. The Oregon projection matched the True Vote Model and was within 1.6% of his recorded share.
In the final weeks prior to the 2004 and 2008 elections, national LV polls were displayed on political websites; many did not allocate undecided voters. By virtue of its vote by mail system, Oregon’s RV pre-election polls undermine the media’s objective of forcing voters into believing bogus vote counts. The media primes voters before the election with LV-only projections. Then it covers up the fraud post-election with final “exit polls” that are always forced to match the counts. In 2008 National Election Pool (NEP) consortium did not release the preliminary national and unadjusted state exit polls. Why not?
1988 – 2008: Patterns of Discrepancies Before and After Voting-By-Mail
Before Mail-In Ballots
1988 – Bush was Vice President. Dukakis had 51.3% in Oregon and 45.7% National. He did 3.2% better in the OR exit poll.
1992 – Bush was President. Clinton had 42.5% in Oregon and 43.0% National. He did 5.1% better in the OR exit poll.
1996 – Clinton was President. He had 47.2% in Oregon and 49.2% National. He did 2.2% better in the OR exit poll.
After Mail-In Ballots
2000 – Clinton was President. Gore had 47.0% in Oregon and a 48.4% National share
2004 – Bush was President. Kerry had 51.3% in Oregon and a 48.3% National share
2008 – Bush was President. Obama had 58.4% in Oregon and a 52.9% National share
- Is it just a coincidence that when Clinton was the incumbent, there was just a 1.7% deviation between the Oregon and National vote shares?
- Is it just a coincidence that when Bush was the incumbent, there was a 3.5% deviation between the Oregon and National vote shares?
- If the True Vote Model is correct and Oregon reflects the national electorate, then what does it say about our electoral system?
Oregon County Vote Change Correlation
With the change to mail-in ballots in 1998, there has been a noticeable decline in the volatility of changes in Oregon county vote shares from election to election. Before the switch to mail, there was a 0.93 correlation between 1996 and 2000 county vote share and a 5.0% standard deviation.
After the switch to mail, there was a near-perfect 0.98 correlation between 2000 and 2004 county vote shares and a 2.2% standard deviation in percentage vote change. There was an even better 0.99 correlation for 2004 and 2008 and a very low1.5% standard deviation in percentage vote change. The system is getting better and better.
The statistical analysis makes intuitive sense. Since the battleground states closely mirror the national electorate as a whole, Oregon’s recorded vote share should have been close to that of the other battleground states, but it was the only one that deviated sharply to Kerry. Oregon’s voting system is transparent. Optically scanned machine counts are verified by random hand-counts. Washington has also recently implemented a mail-in system.
Touch screen voting machine precincts avoid paper ballots; votes can be switched locally or at the invisible central tabulators. Optical scanners are a step in the right direction, but the system is ripe for fraud without mandating a random hand-count of selected precincts like they do in Oregon. Punch card machines can void the vote by double and triple-punching after the polls close. As in Florida 2000, election officials are quick to blame “stupid” voters if there are “problems” with the machines.
If they use lever machines, as in NY and PA, there are no paper ballots to verify the vote; too few machines can be placed in heavily Democratic precincts; or bad machines that will likely break down will cause voters to leave the polling booth; the levers can be “stuck”, like they were for Bush in 2004; votes can be switched by the central tabulators; lever gears can be shaved. There are many ways to skin the cat. In NY, Gore, Kerry and Obama each enjoyed a 7% higher late (paper ballot) vote share than they did on Election Day (lever votes). What does that tell us?
Here is an amazing statistic that very few are even aware of: Obama had 52% of the 121 million votes recorded on Election Day and a whopping 59% of the 10 million late (paper ballot) votes. What are the odds of the 7% discrepancy? What is the margin of error in a poll with 10 million respondents?
Since Kerry won new voters by 59-39% and returning Nader voters by 65-13%, to believe the recorded vote shares, you must also believe that returning Gore voters defected to Bush at a much higher rate than Bush voters to Kerry. But according to the National Exit Poll, 10% of Bush and 8% of Gore voters defected.
The above analysis indicates that Oregon’s mail-in system works just fine. But it would be greatly appreciated if interested readers found flaws in the assumptions, logic or the math and presented contrary statistical and/or anecdotal evidence. The analysis can then be forwarded to Oregon’s election officials who may then decide to scrap vote by mail and convert to HAVA-compliant DREs, Optical scanners, Punch cards or Levers. Advise them to recount only those elections in which the vote shares differ by less than .001%.
If you believe the recorded 2004 vote was accurate in the battleground states, then you must also believe that…
1- Bush won a fair election.
2- The electronic and mechanical voting machines accurately counted the votes.
3- There was little or no fraud.
4- Election reform efforts are meaningless.
5- There is nothing wrong with our national voting system.
6- Oregon’s voting system was rigged for Kerry since it was the only battleground state he won that shifted sharply to him from Gore.
7- Pre-election state and national polls that projected Kerry would win by 51-48% after undecided voters were allocated were wrong.
8- Unadjusted and preliminary state and national exit polls that had Kerry winning by 5-7% were wrong.
9- The Oregon telephone survey that showed Kerry winning a 52.3% share was wrong.
10- Either returning Nader voters defected to Bush and/or he won a majority of new voters and/or more returning Gore voters than Bush voters defected.
11 -The National Exit Poll which had Kerry winning returning Nader voters by 65-13% and new voters by 59-39% were wrong.
12- The Oregon vote must have been padded for Kerry (51.4%) and Obama (56.7%).
13- Election officials in Florida, Ohio, NY and other states did a great job in making sure that the voting machines were not tampered with.
14- A problem with vote by mail is the elimination of exit polls. Oregon needs exit polls even though they are usually wrong.
15- The True Vote Model is flawed since it closely matched the unadjusted National, Oregon and Battleground exit polls.
16- There is nothing wrong with the standard policy of forcing final state and national exit polls to match the recorded vote.
17- Final 1992, 2004 and 2008 National Exit Polls were correct: there were millions more returning Bush voters from the prior election than were alive.
If you believe that vote-by-mail systems are vulnerable to election official fraud or voter fraud, then lobby state officials to stop the vote-by-mail trend. Otherwise, fraud-free HAVA-compliant voting systems now working just fine in all the other states will become clones of Oregon and Washington.
Those opposed to mail-in voting cite advantages in voting at the precinct: voters can get to see friends and make new ones, take time off from work, project a patriotic image by voting in full view, look smart by touching the computer screen, exercise their legs while waiting to vote and get some cheap coffee.
