“Who is trying to knock him out?”

Rubio and the Huckster for the most part. And since Huckleberry isn’t going anywhere he’s mostly just shilling for Rubio.
That’s really disappointing about Huckabee; he comes across in the debates as all “I’m too principled to ever attack a fellow Republican” and then secretly does it with big bucks in private. What a snake! No wonder he and Rubio pair up so nicely.
