Obama goes "47%" on Romney in new TV spot

Barack Obama's campaign is up with a new TV ad that hammers Mitt Romney's "47%" comments as insensitive to low-income workers.

It's a strong ad, but it finishes with the obligatory shout-down of Mitt's tax rate last year. It's a ubiquitous personal attack from Obama, but just because it might be working doesn't mean it's any less a trivial issue  in the context of a presidential race.

The ad will run in the usual slate of battleground states -- Ohio, Nevada, Colorado, Iowa, New Hampshire, Florida, Virginia, and North Carolina.

As Alex Roarty notes, Wisconsin is a glaring omission, and might be a sign that the Obama campaign thinks things are a bit more comfortable there now.
