CNN has released a poll that puts three candidates from last year’s Presidential elections in a dead heat for the 2012 GOP nomination:

The survey suggests that 22 percent of Republicans would most likely support former Arkansas governor and former GOP presidential candidate Mike Huckabee for their party’s presidential nomination in 2012. Twenty-one percent say they would most likely back Alaska governor and 2008 Republican vice presidential nominee Sarah Palin, with an equal number supporting former Massachusetts governor and former White House hopeful Mitt Romney.

Taking into account the poll’s 4.5 percent sampling error, Huckabee, Palin and Romney seem to be locked in a hypothetical dead heat.

Former Speaker of the House Newt Gingrich and former Florida governor Jeb Bush also received support in the poll, which was released the same day that Minnesota governor Tim Pawlenty said he won’t be running for reelection next year.

Pawlenty’s move is seen as a precursor to a run for the GOP nomination, as he would be avoiding a potentially difficult reelection race in Minnesota.

Any surprises?
