New Obama ad lets Mitt Romney destroy himself in his own words

The toughest ad of the 2012 election comes from the Obama campaign ... and it features nothing but Mitt Romney's own words writing off the 47 percent alongside images of the very people'seniors, veterans and regular Americans'who he's attacking:

Transcript:

MITT ROMNEY: There are 47% of the people who will vote for the president no matter what ... who are dependent upon government, who believe that they are victims, who believe that government has a responsibility to care for them, who believe that they are entitled to health care, to food, to housing, to you-name-it ... And they will vote for this president no matter what ... And so my job is not to worry about those people. I'll never convince them they should take personal responsibility and care for their lives.

It's not often that a political campaign's best surrogate is the opposing candidate, but that's the case in 2012. Nobody has delivered a more devastating attack on Mitt Romney than Mitt Romney himself.

The ad will air in Ohio, Virginia, Florida, Iowa, Colorado, Nevada and New Hampshire.
