WASHINGTON, Dec. 2 (UPI) -- The campaign of Republican U.S. presidential candidate Mitt Romney experienced a few missteps this week, exposing possible signs of strain, observers note.
GOP hopeful Newt Gingrich climbed in the polls and Democrats picked up their attacks on the former Massachusetts governor, taking him to task for flip-flopping on issues and critical of an ad his campaign he admits is misleading. He also showed irritation during a national interview.
