Martial artist and actor Chuck Norris has lent his voice to a robocall, promoting Newt Gingrich to Mississippi and Alabama voters. Norris says he and his wife decided, based on the many Republican debates, that, of the candidates, Gingrich "would be best to do head-to-head combat with President Obama. Now, I didn't say hand-to-hand combat, though I think they would win there too."
