Palin looks to be stealing Huckabee's thunder among Republican religious conservatives and working class voters. Huckabee is an ordained Southern Baptist minister, and his highest GOP totals still come from Born-Again Christians (15 percent) and weekly churchgoers (18 percent), but those numbers are about half of those drawn by Palin.
2) Mitt Romney has the most diverse appeal.
Romney's Republican support level is very consistent across demographic groups. Among his party members, Romney's numbers fall off by a few points from his overall 18.1 percent with religious conservatives and gun owners.
