CNN has Obama gaining 3 points, for a 7 point lead and Fox has Obama gaining 5 points for a 9 point lead. Now where did those extra margins come from? Not from more favorable opinions of Obama’s performance as president.
CNN actually has Obama losing a point on approval while Fox has him gaining slightly. But now look at how Romney’s favorables have performed:
He went from +6 to -1 in the CNN poll (a -7 point swing) and form +12 to +1 in the Fox poll (a -11 point swing). And it has been independents that have soured on Romney the most. Here is the Fox News vote preference breakdown:
Romney’s position among Republicans and Democrats was virtually unchanged. But he went from -4 among Independents to -11 (a -7 point swing). And why did independents sour on Romney? Obama has driven his unfavorables up substantially:
Again, Romney’s position among Republicans was unchanged and Democrats now view him a bit more unfavorably, but the major movement is among independents who went from +12 pro-favorable opinion of Romney to just +1, a -11 point swing.
