Republican presidential candidates Mitt Romney and Newt Gingrich mixed it up early in a debate in Iowa Saturday, with Romney accusing Gingrich of far-fetched ideas such as mining minerals on the moon.
Romney said the bigger difference is that he offers decades of experience as a private sector executive, while Gingrich was a Washington insider.
Gingrich, the former House speaker ahead in Iowa, countered that Romney would have become a Washington insider had he not lost his U.S. Senate bid in 1994.
"The only reason you didn't become a career politician is because you lost to Ted Kennedy in 1994," Gingrich said.
Romney quickly retorted: "If I'd been able to get in the NFL as I'd hoped as a kid, I could have been a football star too."
