Larry Sabato: Only 3 Republicans Can Win Nomination - Jeb Bush, Marco Rubio and Scott Walker

Sabato is asked by Cavuto about Ted Cruz and Rand Paul

Larry says Cruz 'certainly excites conservatives' but he is 'redder than red.'  Sabato says he's not sure if the country is there.  About Sen. Paul, Larry Sabato believes Rand 'divides' the Republican party on issues such as national security and foreign policy, making it difficult to come together for a general election against Hillary.

As of now, it's Walker, Rubio or Bush
