The latest CBS poll shows Herman Cain surging 12 points and Rick Perry dropping 11 points while Mitt Romney holds steady:
Herman Cain has moved into a tie with Mitt Romney atop the field of Republican presidential candidates, according to a new CBS News poll, while Rick Perry has fallen 11 percentage points in just two weeks.
The poll shows Cain, who stood at just five percent support two weeks ago, now holding 17 percent support among Republican primary voters. That puts the former Godfather's Pizza CEO into a tie with Romney, the former Massachusetts governor, whose support has essentially held steady over the past two weeks.
Perry, meanwhile, has dropped from 23 percent support to just 12 percent support over the past two weeks...
Eighteen percent of Republicans remain undecided.
