Five Thirty Eight rates the candidates:
- B+: Marco Rubio
- B-: Rand Paul, Ted Cruz
- C+: Jeb Bush, Carly Fiorina, Donald Trump, Ben Carson
- C: John Kasich
A much better debate than last time, with actual policy exchanges rather than gotcha questions.
Bush has kept his campaign alive. Rubio still looks like the most likely eventual candidate. Cruz has another good performance and for the first time Rand Paul has a good debate.
