Results of a national Fox News poll released today show former Massachusetts Gov. Mitt Romney retaking the lead in the field of Republican presidential hopefuls.

Romney polled at 23 percent according to the new poll, inching over Perry's 19 percent vote share. Romney only gained 1 percent since the last Fox News poll in August, but Perry sunk by 10 points, resulting in the reshuffling of the field.

Romney was the frontrunner early in campaign season, enjoying a sizable lead over his fellow candidates thanks to his name recognition and past experience as a state executive.

However, when Texas Gov. Rick Perry entered the race, the polls suddenly shifted. Within two weeks of his official announcement, he had rocketed to the top slot: Perry was the choice of 29 percent of Republicans polled, leaving Romney and his newly diminished 17 percent vote share in his dust.

The new Fox News poll is to be taken with a grain of salt, however, in context with other national polls. For example, Fox's new poll shows Godfather's Pizza CEO Herman Cain third in the field, at 17 percent — triple his vote share in the organization's poll last month. A CNN/ORC poll released earlier this week, however, show Cain with only 7 percent of the vote, and Perry holding strong in the lead. Perry held 28 percent of the vote, while Romney garnered 21 percent.
