WASHINGTON (CNN) – A new national poll indicates that more than seven out in 10 Republicans say they would seriously consider voting for Mike Huckabee for president in the next race for the White House, giving the former Arkansas governor more potential support than Sarah Palin, Mitt Romney, or any other Republican tested.

But the USA Today/Gallup survey released Wednesday morning also suggests that none of those potential Republican hopefuls could win the votes of a majority of all Americans if they won the GOP nomination in 2012.

The poll finds that 71 percent of Republicans questioned say they would seriously consider voting for Huckabee, the former governor of Arkansas and 2008 GOP presidential candidate.

Sixty-five percent say they would seriously consider voting for Romney, the former Massachusetts governor who also ran for the 2008 Republican presidential nomination. An equal amount indicate they'd seriously consider voting for Palin, the former Alaska governor who served as John McCain's running mate last year. Six in 10 saying they would take a serious look at voting for former House Speaker Newt Gingrich, but far fewer respondents say they would support the much less recognized Minnesota Gov. Tim Pawlenty (32 percent) or Mississippi Gov. Haley Barbour (26 percent).

Among all Americans, the poll suggests that only around four in 10 would seriously consider backing Huckabee or Romney, with one in three saying they would seriously support Palin, 29 percent seriously considering voting for Gingrich and less than one in five backing Pawlenty or Barbour.

"The latest CNN/Opinion Research Corporation poll had Huckabee ahead of Palin and Romney in a head-to-head match-up among Republicans," says CNN Polling Director Keating Holland. "So Huckabee not only has more support now, but the potential to gain even more backers that his possible opponents as 2012 approaches."

These surveys are very early hypothetical looks at the next race for the White House. It's the pre-season in the next presidential contest, as possible GOP contenders form political action committees, campaign for fellow Republicans, write books and address conservative conferences and party dinners.

The USA Today/Gallup poll was conducted October 31-November 1, with 1,021 national adults questioned by telephone. The survey's sampling error is plus or minus 4 percentage points for the overall sample and plus or minus 7 percentage points for questions of Republicans only.
