Ron Paul at 7 percent in the poll.

Mitt Romney and Sarah Palin are the clear leaders of the 2012 Republican presidential primary field, according to a new Gallup poll out Thursday. Thirteen Republicans received support in the survey, demonstrating the wide open nature of the field, but Romney and Palin were the only potential candidates to earn more than 15 percent in the poll, with Mike Huckabee trailing not far behind. The three former governors were the only candidates to receive more than 10 percent, with Romney receiving 19 percent, Palin getting 16 percent and Huckabee at 12 percent. Former House Speaker Newt Gingrich came in fourth in the poll, getting 9 percent.Link
