According to the latest Post/ABC poll, over the past two weeks Obama has gone from two points down to 9 points up (47-49 to 52-43). The WaPo headline attributes the shift to the economy, which is now the top concern of 50 percent of respondents, up from 37 percent. And, indeed, Obama’s edge on handling the economy has jumped nine points. But here’s what I’d be most worried about if I were McCain. Two weeks ago, respondents thought he was more honest and trustworthy than Obama by a 44-38 margin. In the current poll, Obama leads 47-36. Straight talk has always been McCain’s stock in trade. The stock’s down, a lot.
