Rick Perry Takes Aim at Mitt Romney in New Web Ad

Reeling from a near-universally panned performance in Thursday nights debate and finishing distant second in straw polls in Florida and Michigan over the weekend, Texas Gov. Rick Perry took aim on Monday at his closest rival for the Republican presidential nomination -- former Gov. Mitt Romney of Massachusetts.

The Perry team released a web video hammering Romney for changing the wording of various editions of his book -- something Romney accused Perry of in the debate on Thursday.

"Mitt Romney may try to edit his past, but he can't; President Obama followed Mitt Romney's model of Romneycare when he designed Obamacare," said Mark Miner, a spokesman for Perry, in a statement. "Americans are looking for a proven and authentic conservative, not someone who changes his policies based on the 'climate.'"
