Chuck Norris is back on the campaign trail. The actor and martial arts expert who stumped for Mike Huckabee during the 2008 presidential campaign is headed again to Iowa, this time to appear with Republican gubernatorial candidate Bob Vander Plaats. Vander Plaats was Huckabee's Iowa chairman when the former Arkansas governor won an upset victory there; now, Vander Plaats faces his own uphill battle against former Gov. Terry Branstad in the GOP primary. Norris will make campaign stops on June 4 and 5, just ahead of the June 8 primary.
