Mitt Romney isn't the only candidate with a healthcare problem in the GOP primary.
One-time front-runner Rick Perry, in part of a furious bid to make up ground before the Iowa caucuses, is linking Newt Gingrich to Romney and President Obama in a new television ad.
"We don't want government-mandated healthcare. Yet Newt Gingrich supports it. And Mitt Romney? He put it into law in Massachusetts," the narrator says.
Perry himself then says he "won't let the big government liberals ruin this country," and promises to repeal Obama's healthcare law.
