WASHINGTON (AFP) - The 2016 US election might be a full three and a half years away, but that is not stopping pollsters from asking voters who has the early presidential edge. And the advantage goes to Hillary Clinton. The recently retired secretary of state and former first lady would handily defeat any of three leading potential Republican candidates, including New Jersey Governor Chris Christie, the Quinnipiac University poll said Thursday. The blunt-talking Christie came in second in the poll , well ahead of fellow Republicans Marco Rubio, a first-term senator from Florida, and congressman Paul Ryan, who was Mitt Romney’s running mate in 2012.
