That just maybe Gleason might be wrong about the cause of the margin differences?
In point of fact, Obama's margins in a number of places was less than it was in 2008. His popular vote margin nationally in 2008 was 7.3 percent, and only 3.85 percent in 2012.
In Illinois, a generally Democratic state with no voter ID law, the popular vote margin for Obama was 25 points in 2008, and only 17 points in 2012.
