Ambers analyzes the horserace:
The most interesting number in the latest NBC News/Wall Street Journal poll has 62 percent of the electorate begging for a major change in policy of the next four years. That number obviously includes Democrats. Right now, Obama's campaign is pounding Mitt Romney for having a plan (fact: he has one) that doesn't add up or furthers the plutocracy. Fine. But the line of attack that Romney is using — that the only thing Barack Obama offers is more of the same — is more damaging, because even a lot of voters who already support President Obama really want to see something different from him. Obama does have a "plan," but his team has decided that it's not a priority right now to communicate it. That may be a mistake.
