In this Sept. 25, 2012, photo, Missouri Republican Senate candidate, Rep. Todd Akin, R-Mo., speaks during a news conference at the start of a statewide bus tour in St. Louis. Akin has backed millions of dollars of earmarks in recent years. He even proudly defended an earmark for military armor during a TV ad in his Republican Senate primary. Now Akin has aligned himself with a group that wants to ban earmarks. And the membership of the Senate Conservatives Fund has pledged $290,000 to help finance his campaign against Democratic Sen. Claire McCaskill. Akin denies he has flip-flopped and rejects any assertion of a quid pro quo for campaign cash. (AP Photo/Jeff Roberson)
