New polls show Romney is strong in three early-voting states.
WASHINGTON (CNN) - A new survey is highlighting the fluid nature of the GOP presidential race in three early-voting primary states.
In Iowa, the AP-Pew poll released Tuesday says the national front-runner, former New York City mayor Rudy Giuliani, trails former Govs. Mitt Romney of Massachusetts and Mike Huckabee of Arkansas. Romney is also in contention for the top spot in New Hampshire and South Carolina.
But no lead is safe. Just 57 percent of Iowa Republicans say they strongly support their currently-favored candidate. The race is even more chaotic in New Hampshire and South Carolina, where just 49 and 44 percent of voters are certain of their choice.
Giuliani is viewed as the most electable candidate by Iowa and South Carolina Republicans and is tied with Romney in that category in New Hampshire. But solid majorities in each state say finding a candidate who shares their stands on the issues is a more important consideration.
In Iowa, Romney has 25 percent support among Republicans, Huckabee 24 percent, Giuliani 14 percent and former Tennessee Sen. Fred Thompson 12 percent.
In New Hampshire, Romney has 37 percent, Giuliani 19 percent and and Arizona Sen. John McCain 15 percent.
In South Carolina, where the poll shows voters are less focused on the race, Romney and Giuliani have 19 percent each, Thompson 18 percent, McCain 13 percent and Huckabee 10 percent.
The poll, which was conducted over a lengthy two-week period early this month, may have failed to capture Mike Huckabee’s late gains in Iowa. But it does capture deep divisions among traditional Republican blocs, with no one candidate capturing a majority of evangelicals, conservatives or men. Republicans who go to church at least once weekly prefer Huckabee in Iowa, Romney in New Hampshire, and Thompson in South Carolina.
The survey of likely voters in Iowa had a margin of error of plus or minus 7 percentage points. The margin of error in New Hampshire and South Carolina was 5.5 percent.
