Obama for America, Made in Ohio

What it says: “Mitt Romney would have just let us go under- just let them go… bankrupt." Over a map of Ohio, the text at the end reads, "Mitt Romney. Not One of us." 

What it means: President Obama's campaign has attacked Romney over the auto bailout before, but this ad is particularly harsh. (Our Fact Checker has explained that Romney called for a "managed bankruptcy," not liquidation. But many independent analysts say that that approach would not have worked in 2008.)

Who will see it: Do you really have to ask? (It's Ohio.)
