瑞克也退出了，只剩下4个了

(CNN) – Texas Gov. Rick Perry suspended his struggling presidential campaign Thursday and threw his support to Newt Gingrich, a development that could alter the dynamics of the Republican race just two days before the tightening South Carolina primary.

"I believe Newt is a conservative visionary who can transform our country. We've had our differences, which campaigns will inevitably have, and Newt is not perfect, but who among us is?" Perry said at a press conference in Charleston, South Carolina.
