Romney holds lead in Iowa

The latest poll out of Iowa show that Mitt Romney is holding his lead in the first caucus state.

The former Massachusetts governor led with 33 percent of likely Republican caucus-goers, well ahead of former New York Mayor Rudy Giuliani with 14 percent, former Tennessee Senator Fred Thompson (not officially in the race yet) with 12 percent, former Arkansas Governor Mike Huckabee with 8 percent, and Arizona Senator John McCain with 6 percent.

The Newsmax/Zogby survey, released today, was conducted on Aug. 17 and 18 among 487 Republican voters and has a margin of error of plus or minus 4.5 percentage points.

Romney trails Giuliani and McCain in national polls, but has spent much more time and money in Iowa than his competitors. Earlier this month, Romney won the Iowa straw poll, which Giuliani and McCain skipped.
