A new poll from Public Policy Polling shows that Ron Paul has taken the lead in the Iowa caucus race, while Newt Gingrich's support is fading fast. A different Gallup poll shows Grinrich still holding the lead, but slipping, while The New York Times has Paul in the lead as well.
Gingrich has seen his numbers in the PPP poll drop from 27 percent to 14 percent in just three weeks, while his favorability rating is now split at 46 percent for to 47 percent against, the worst of any candidate not named Jon Huntsman. That's quite a fall for someone who looked to be running away with the state and taking charge on the national level.
Mitt Romney has also seen his numbers tick up slightly (to 20%), putting him just behind Paul (23%) for second place. The poll measured voters who are planning to vote in the Republican caucus.
Perhaps the most telling secondary question was, "Do you think Newt Gingrich has strong principles?" Only 36 percent say that he does, but for Paul that number was 73 percent.
