Rubio hasn’t seemed to be focusing on much of anything since Crist dropped out. But to the degree he is going after Crist, that is exactly what he should be doing, because he doesn’t have a contest in the primary, and acknowledging a non-factor just causes primary trouble.
And for all we know, Rubio could like his primary opponent, and have nothing bad to say about him, so what would he do anyway?
an interesting point... The voters will decide on August 24th that is for sure..
