Scott Walker leads big in Iowa

New Jersey Gov. Chris Christie (R) sits at 9 percent, with Sen. Marco Rubio (R-Fla.) and former Arkansas Gov. Mike Huckabee (R) at 7 percent, former Sen. Rick Santorum (R-Pa.) at 6 percent, Dr. Ben Carson at 5 percent, Sen. Ted Cruz (R-Texas) at 4 percent and businesswoman Carly Fiorina at 3 percent.

In general election matchups, former Secretary of State Hillary Clinton continues to show strength in Iowa. She leads Walker 47 to 41 percent and has an edge against all of her other potential GOP foes.

The results are the latest to show Walker on the rise, though these are much better numbers for him than other recent surveys that have found no candidate higher than the mid-teens.
