The former super-PAC of possible presidential candidate Stephen Colbert, “Americans for a Better Tomorrow, Tomorrow,” now in the hands of Jon Stewart, is definitely not coordinating with Colbert. The committee’s own website says so! Although that’s settled, Colbert’s candidacy in South Carolina is in trouble because he’s not on the ballot. But Herman Cain is, and the Cain Train is elsewhere riding around on his Solutions Revolution tour, so Colbert has decided to campaign under Cain’s name. Following up on its “Mitt Romney Is a Serial Killer” ad, the super-PAC released another spot today, “Not Abel,” which establishes Colbert’s new strategy.
