Marc Ambinder has the unofficial results.
Romney wins with 31% and a paltry 4,516 votes -- far under his campaign's predictions. Huckabee placed second with 18.1% with 2587, but not too far ahead of Brownback (15.3%) and Tancredo (13.7%). Don't expect any of them to drop out yet.
Ron Paul (9.1%) will continue to raise eyebrows and Tommy Thompson (7.3%) will almost certainly drop his bid now.
