Of Course the Game is Rigged
Jim Geraghty compares the 2008 results to the 2012 polls:
Ohio 2008 exits: 39% Democrat, 31% Republican, 30% Independent.
Ohio New York Times/Quinnipiac 2012 sample: 35% Democrat, 26% Republican, 35% Independent.
In this sample, the partisan split is D+9 compared to D+8 four years ago, and the GOP is five percentage points smaller than in 2008.
Pennsylvania 2008 exits: 44% Democrat, 37% Republican, 18% Independent.
Pennsylvania New York Times/Quinnipiac 2012 sample: 39% Democrat, 28% Republican, 27% Independent.
Somehow a D+7 split has turned into D+11 split, and Republicans’ share of the electorate is nine percentage points less than they were four years ago.
Florida 2008 exits: 37% Democrat, 34% Republican, 29% Independent.
Florida New York Times/Quinnipiac 2012 sample: 36% Democrat, 27% Republican, 33% Independent.
Each party’s share only shifts a few percentage points, but the overall split goes from D+3 to D+9.
I've never seen anything like this.
