Poll Context: After an extraordinary day where earlier Mitt Romney attacked Donald Trump harder than he ever attacked Barack Obama or Hillary Clinton and the day where he implored the other candidates to work together to prevent Trump from winning enough delegates to secure the nomination and force a ‘brokered convention’, the long awaited Fox debate took place. Marco Rubio explained his turned around from his not attacking other candidates to his school yard insults of recent day byt saying that Trump started it and he deserved it. But his voice was hoarse and depleted of its energy. The zingers he happily slung at Trump last time around seemed tired and worn. All of the optimism surrounding Rubio’s campaign following all of that establishment support and the attack dog tactics against Trump seems to have vaporized since Super Tuesday. Nearly every poll after the debate showed Rubio in last place. So, is it time for him to quit the race?
