The Des Moines Register has released i ts new Iowa Poll, conducted May 12-16 by Selzer & Co. among 400 likely caucus-goers, with a margin of error is +/-5%. The poll shows Gov. Romney in the lead with 30%, followed by McCain at 18%, Giuliani at 17%, Tommy Thompson at 7%, and Brownback at 5%. Huckabee and Tancredo are at 4%. Twelve percent of voters are undecided.

Good news for Romney, needless to say. I’ll be curious to know how Thompson makes a Des Moines Register poll look in a month, in two months.
