If you didn’t even know McCotter was running for president, you’re probably not alone. He was never in a debate and barely registered in polls. He placed tenth in Iowa’s Ames straw poll, with 35 votes.

McCotter, a five-term lawmaker known mostly for his quirky one-liners and sideline in rock music, says the press did him in.

“If they keep you out of the debates, you are out of the conversation and you can’t run,” McCotter told the Detroit News. “It was sort of death by media.”

The Romney endorsement is somewhat surprising. In his brief campaign, McCotter attacked Romney regularly, once suggesting that his rival could be President Obama's running mate. Now he calls Romney “the most electable.”

McCotter said in a statement that he would seek reelection to his 11th district seat.
