Rubio, Carson, and whats his name need to drop out and back Cruz. He is the only one that has a chance of beating Trump and the longer they wait the harder it will be. Trump is even ahead in the polls in Rubio's home state of Florida.
This. If Rubio can't even dominate his home state, he doesn't have any political capital to trade on. The GOP has to decide which of three really unpleasant things they want to have happen. That thought makes me warm inside.
