John McCain's standing has dropped in Iowa among Republican contenders in the presidential race.
A new poll shows ratings for the Arizona senator, once viewed a front-runner for the nomination, in the single digits. At the head of the GOP pack is Mitt Romney. Fred Thompson, the actor-politician who hasn't formally said he's running, is tied for second with Rudy Giuliani.
The poll was done after Giuliani, a former New York City mayor, and McCain said they would skip the Iowa straw poll in August.
Among Democrats, Hillary Rodham Clinton, John Edwards and Barack Obama were bunched at the top.
