New Jersey Gov. Chris Christie seemingly was able to get the upperhand over Sen. Marco Rubio during Saturday's Republican presidential debate for Rubio's laser-like focus on pivoting to criticize President Barack Obama. A day later, Rubio is sticking by that strategy. On ABC's "This Week," George Stephanoplous noted to Rubio on Sunday that his opponents had continued to follow Christie's example and batter Rubio as being a "robot.""As far as that message.
