Texas Gov. Rick Perry will drop out of the presidential race Thursday, according to people familiar with his decision.

Mr. Perry will endorse Newt Gingrich for the Republican nomination, a senior figure in the governor’s campaign said. The endorsement comes just as polls suggest that Mr. Gingrich is closing in on front-runner Mitt Romney in South Carolina as voters prepare to cast ballots here Saturday.

Mr. Perry will hold a news conference at 11 a.m. to announce his decision, people familiar with the matter said. More Here.
