Rick Perry was the second presidential contender to speak at the "Values Voter Summit" in Washington, D.C, on Friday. He touted his economic record as governor of Texas, touched on border security and took what seemed to be a swipe at Mitt Romney.

"For some candidates, 'pro-life' is an election year slogan," Perry said. Romney has faced criticism for contradictory statements he's made on abortion as governor of Massachusetts and as a candidate for president.

Perry also said that all voters are "values voters." The difference is, he said, "whose values?"
