The candidates are desperate and are going after the leader Trump and trying to knock him down. Trump will fight and fight hard.
Yep, South Carolina is a pivotal battle for most of them. If Trump dominates he rolls his way to the nomination. And he's already playing for the general election voters. Cruz and Jeb still have a ton of cash. Cruz will run out quickly if he loses big in South Carolina. Rubio and Bush will fight it out for the GOPe money and it will come down to one of them and Trump.
