I don’t want to pick on Sam Brownback, but right now he’s got 2 percent in the latest Des Moines Register poll.

You know who else has 2 percent? Alan Keyes.

The Register finds Mitt Romney up big, 29 percent to Thompson’s 18 percent, Huckabee’s 12 percent, and Giuliani’s 11 percent.

UPDATE: Another sign your campaign is flailing? Holding a joint campaign event with Democrat Joe Biden in Iowa, talking about their decentralization/partition plan for Iraq.
