As we reported yesterday, the daily (de-trended) Gallup Poll on Obama's job approval showed an amazing spike to 61% approve, 39% disapprove the day before the first debate. Today's numbers are out and the (de-trended) numbers are 46% approve, 48% disapprove, giving a three day average of 52% approve, 43% disapprove.
Despite this wild oscillation in Obama's job approval numbers, the Gallup head-to-head with Romney has not changed in a week and a half. The current numbers are Obama 50%, Romney 45%. So, although it is reasonable to infer that Obama himself took a hit in voter approval, no one changed their mind about how they are going to vote.
So, if the election is not about Obama, then it must be about Romney. There are only two of them after all.
