Kasich needs a good showing
John Kasich is somebody who really seems to have lost any momentum he once had. He desperately needs a good showing tonight if he wants to have any chance of becoming a general election threat, as a poor performance and continued slippage in polls could force him into the secondary debate by next time.
Look for Rubio, Cruz, and Bush to attack each other as well as Trump
The mainstream Republican candidates that look like big election threats right now are Marco Rubio, Ted Cruz, and Jeb Bush. I would expect them to go after each other a lot, as well as Donald Trump.
Carson and Fiorina both have an opportunity tonight
This is a big chance for Ben Carson and Carly Fiorina to paint themselves as outsiders with more reasonable views than Trump. The types of candidates polling well indicates that a lot of people want an outsider in the White House come 2016, leading to the success of Trump and Carson in the early polls.
