Republican presidential candidate Mitt Romney  left, hands 6-month-old Dexter Hall of Plymouth, Minn. back to his mother, Laura, during a campaign stop at Freightmasters, Inc. in Eagan, Minn., on Wednesday, Feb.  1, 2012.  Romney, who won big in Florida with a barrage of negative ads, predicted the tone of the GOP campaign was &quot;just a precursor to what you'll see&quot; from President Barack Obama in the general election. And he said voters paid more attention to what they heard in the campaign debates than whatever ads were flooding the airwaves.
