DES MOINES (Reuters) - Democratic presidential hopeful Hillary Clinton may have shot herself in the foot trying to get Iowa voters to pledge support to her -- she is encouraging them to caucus on January 14, 11 days too late.

At a rally featuring her husband, former President Bill Clinton on Saturday, campaign workers asked supporters to sign and mail cards that said “Yes! I’m an Iowan for Hillary” with their contact information as well as other supportive friends.

One small problem. In the upper right-hand corner of the card, it says “I, _____, pledge to support Hillary Clinton at my precinct caucus on January 14, 2008.”

Unfortunately, that’s 11 days too late. The Iowa caucuses are January 3 and organization is key to getting voters to go to the events and support their preferred candidate.

The Politico.com, an Internet site that specializes in politics and first reported the mistake, said at Bill Clinton’s second event on Saturday the cards had the wrong date crossed out and replaced with the correct date.
