It's official:
Former Tennessee Sen. Fred Thompson quit the Republican presidential race on Tuesday, after a string of poor finishes in early primary and caucus states. "Today, I have withdrawn my candidacy for president of the United States. I hope that my country and my party have benefited from our having made this effort," Thompson said in a statement.
Thoughts on why Fred failed from Jody Bottum here and a different take from Marc Ambinder here. And Geraghty reported earlier today that Fred would not seek the vice presidency or a cabinet position.
