COSTELLO: And good morning. I'm Carol Costello. Thanks for joining me. Say hello to a new surging Republican candidate. Not Rubio. Not Bush. But Senator Ted Cruz. A new Quinnipiac poll has Cruz running neck and neck with Donald Trump in Iowa. Trump still leads when it comes to handling terrorism though, 30 percent of Iowa caucus-goers say they are all in for Trump on that issue. The front runner ramping up his rhetoric on waterboarding at an event last night in Columbus.</s>DONALD TRUMP (R), PRESIDENTIAL CANDIDATE: Would I approve waterboarding? You bet your ass I'd approve it. You bet your ass. In a heart beat. In a heart beat.</s>COSTELLO: But Ted Cruz is hot on Trump's heels. The political outsider earns the highest marks on foreign policy. This is the man who Senator John McCain once called a wacko bird. Cruz embracing the term on tee shirts and according to Yahoo, he even has a black whacko bird hat in his office.</s>SEN. TED CRUZ (R-TX), PRESIDENTIAL CANDIDATE: When I came back to Texas, grassroots supporters went and printed up baseball caps with Daffy Duck on them. It said "Wacko Birds". And if the grassroots, to this day, people make t-shirt saying they're a proud wacko bird.
New Poll: Cruz Now Trump's Chief Rival in Iowa.
