Richard Charnin – Jan.1, 2021
2020 Election Model. View 10 pre-election polls and recorded state votes, party-ID, model popular votes, shares and electoral votes.
1) National Model input data/calculations in row 5, 2) 25 Trump vote share scenarios in row 35, 3) Model output in row 95.
Consider two model scenarios:
1) Trump: 96% of Repubs, 12% of Dems and 57% of Independents. He has 393 EV, 54.6%, 14.7m vote margin.
2) Trump: 96% of Repubs, 10% of Dems and 55% of Independents. He has 389 EV, 53.4%, 11.4m vote margin.
Note: Equal voter turnout is assumed. This is conservative. Republicans turn out at higher rates than Democrats. Therefore, we can assume Trump did better than the results below indicate.
