National Review Online is claiming the oversampling of Democrats this election season is even more than in the 2008 presidential election. Jim Geraghty writes
Since the issue of whether the party ID within polling samples is realistic seems to be the issue of the week, let’s take a look at how these samples stack up to the 2008 exit 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.
