Poll: Cain leads Romney by 10 in Iowa; Perry in fifth

Herman Cain leads the GOP field in Iowa by double digits, according to a University of Iowa poll out today.

Cain gets 37% of likely caucus attendees, 10 points ahead of Mitt Romney, who is at 27%.

Ron Paul is third with 12%, followed by Newt Gingrich 8%.

Rick Perry is all the way down to fifth with just 6% with Michele Bachmann behind him at 4%. Rick Santorum, for all the time he's spent campaigning there, is at 3%.

For all the talk of Republicans' dissatisfaction with the field, 86% say they're somewhat or very satisfied with it.
