Romney compares Obama to Kim Kardashian

At a campaign stop in Iowa, former Massachusetts Gov. Mitt Romney accused Barack Obama of failing to fulfill the promises he made as a candidate four years ago.

"I've been looking at some video clips on YouTube of President Obama, then candidate Obama going through Iowa making promises," he said.

"I think the gap between his promises and his performance is the largest I've seen, well, since the Kardashian wedding and the promise of until death do we part."

Romney’s wife, Ann, later told Fox News that said she “got a kick out of” the joke.

“The thing people don't know about Mitt is that he likes to have fun, he likes to make jokes and he loves humor," she said.
