VIDEO----> Rick Perry Endorses 'Consistent Conservative' Ted Cruz

Former Texas Gov. Rick Perry is throwing his support behind fellow Texan -- Sen. Ted Cruz -- in the race for the Republican presidential nomination.

The Lone Star State endorsement marks one of Cruz's most high-profile backers and aims to give his campaign a much-needed boost just one week before the crucial, first-in-the-nation caucuses in Iowa.

"Of those individuals who have a chance to win the Republican primary, at this juncture, from my perspective, Ted Cruz is by far the most consistent conservative in that crowd," Perry told Politico on Sunday night. "And that appears to be down to two people."
