Marco Rubio spent much of his presidential campaign trying to ignore Donald Trump.<br />Now he can barely get through five minutes without insulting or attacking the GOP poll leader.<br />Days before Super Tuesday, when 12 states and one territory cast their votes, the Florida senator has turned his campaign into a riposte to Trump’s dominance in the Republican field.<br />But unlike the half-dozen candidates who have followed similar routes, Rubio is aiming to beat Trump at his own game.<br />Peppering his stump speech with broadsides at the front-runner, Rubio has called Trump a hypocrite, accused him of weakness, and even questioned his manhood.<br />“You know what they say about men with small hands,” Rubio said in Roanoke Sunday evening, complete with a pregnant pause.<br />“You can’t trust ‘em.”
