2012 Election Model Post-Mortem: Exactly right at 332 EV
Obama won by 5 million recorded votes with 332 EV. But he did much better than that, just as he did much better than his recorded 9.5 million margin and 365 EV in 2008.
The recorded result was confirmed in the 2012 Election Forecast Model. Obama had 332 electoral votes based on the recorded vote total – not the True Vote. Obama was able once again to overcome the built-in fraud factor, which is reflected by a red-shift in the unadjusted exit polls.
But to paraphrase what Alec Baldwin told the real-estate salesmen in the famous opening scene of the classic film Glen Garry Glen Ross: “These are the unadjusted exit polls. They are gold – but you don’t get them. They’re for NEP only”.
The red-shift did not go away, even though the unadjusted exit polls (in just 31 states this time) have not been released. The recorded vote was projected based on the pre-election LV polls. The Monte Carlo Simulation derived Obama’s 99% win probability and exactly forecast his 332 (snapshot) EV.
But the True Vote Model forecast was 55-45% and 380 EV.
The expected theoretical 321 EV was calculated as the product sum: EV= ∑ P(i)* EV (i), i =1,51 states. The probability P(i) of winning the state’s electoral vote E(i) is based on the 2-party poll projection.
Obama had 51.9% of the two-party recorded vote. To match the recorded vote, Romney needed 17% of returning Obama 2008 voters and 50% of new voters. Romney needed a 2% turnout rate advantage of returning McCain voters over Obama voters. These are implausible vote shares, indicating that Obama did much better than the recorded vote. He won the True Vote by 56-44% (two-party).

Pre-election pollsters anticipate the red-shift without saying so. The Likely Voter Cutoff Model (LVCM) reduces Democratic turnout in LV polls. And the polling samples are based on previous election demographics in which recorded votes are always inflated for the Republicans.
As usual, the pollsters accurately projected the recorded vote. Also, as always, they avoided a True Vote analysis. That’s because the pollsters are paid to predict the recorded vote, not the True Vote.
