Colbert Super PAC attack ad: 'Romney is a serial killer'

The Super PAC founded by Comedy Central host Stephen Colbert has launched its first ad in South Carolina attacking Republican presidential candidate Mitt Romney as "Mitt the Ripper" for his record of destroying businesses as the head of Bain Capital.

Speaking at the Iowa State Fair last year, Romney that "corporations are people."

The ad released Sunday by Colbert's former Super PAC -- renamed Definitely Not Coordinating With Stephen Colbert Super PAC -- contends that if corporations are people "then Mitt Romney is a serial killer."

"He's Mitt the Ripper," the ad, narrated by actor John Lithgow, declares.

Colbert has recently said he was forming an exploratory committee to consider running for president as a Republican in South Carolina. In an effort to mock U.S. election law, Colbert turned his Super PAC over to Comedy Central host Jon Stewart.
