Republican Presidential candidate Ted Cruz has picked up an endorsement from a Republican who dropped out of the GOP race.
FOX's Rachel Sutherland reports from Washington:
Former Republican Presidential candidate and former Texas Governor Rick Perry is throwing his support behind Ted Cruz... telling "Politico" he's more conservative than Trump, who, meanwhile, continues to raise the issue of Cruz's birthplace.
(Trump) "There are a lot of people now that are saying he was born in Canada, he was born on Canada soil, and he cannot run."
Trump on CBS "Face the Nation".
A week before the Iowa caucuses, new FOX polls show Trump surging ahead of Ted Cruz in the state, 34 to 23 percent. Trump also has a double digit lead in New Hampshire.
