Newsweek poll: Huckabee by 22 in Iowa; Obama by 6

Mike Huckabee may be on the verge of wiping out his competition in Iowa, if a new Newsweek poll is correct.

The poll shows Huckabee surging to a huge 22-point lead over Mitt Romney and Rudy Giuliani in single digits at fourth.

Among Democrats, Newsweek has Barack Obama with a 6-point lead over Hillary Clinton.

Republicans
Mike Huckabee, 39%
Mitt Romney, 17%
Fred Thompson, 10%
Rudy Giuliani, 9%
Ron Paul, 8%
John McCain, 6%

Democrats
Barack Obama, 35%  
Hillary Rodham Clinton, 29%  
John Edwards, 18%  
Bill Richardson, 9%  

Huckabee barely registered at 6 percent in the last Newsweek poll in September.

The poll was conducted Wednesday and Thursday so it's hard to say whether the Wayne DuMond controversy has affected Huckabee any. Judging from the numbers probably not -- at least not yet.

One bit of caution, however -- the poll has a rather high MOE of 7 percent among Republicans and 6 percent among Democrats, which could make the Democratic race much closer than it appears.
