The Obama campaign has released a brutal new ad overlaying Mitt Romney’s remarks on the “47 percent” with images of the Americans that Romney disparaged as “victims.”

The ad, titled “My Job,” exclusively features audio from Romney’s secretly recorded fundraiser, and seems certain to be remembered along with Obama’s “Firms” ad as one of the most blunt spots of the year. Greg Sargent reports that it will air in the swing states of Ohio, Virginia, Florida, Iowa, Colorado, Nevada, and New Hampshire.

Earlier this week pollster Stan Greenberg predicted that the 47 percent video would be remembered as the moment that defined the 2012 race, and the Obama campaign seems determined to prove him correct. President Obama’s poll numbers have significantly risen since the video went viral, and unless Romney comes up with an effective response to ads like “My Job,” it’s difficult to imagine him reversing his slide.
