Mitt Romney has been leading the Republican field in Iowa for several months, but the latest University of Iowa poll has measured his lead at nearly three times that of his nearest competitor.
Romney received the support of 36 percent of 282 likely Republican caucus voters, according to the poll, conducted October 17-24 with a margin of error of 5.8 percent. This is the highest number reached by Romney in any public poll in Iowa to date—his previous high was 33 percent in Zogby's August survey.
Rudy Giuliani and Mike Huckabee came in tied for second at 13 percent, followed by Fred Thompson at 11 percent, John McCain at 6 percent, and Tom Tancredo at 2 percent.
Iowans also seem to be settling on a candidate—only 15 percent were undecided as to which candidate they will support, down from 27 percent in the University of Iowa's August 2007 survey.
