He really didn’t have a choice. The lil’ taco bender was just like a mutt yapping at his heels and he would not stop so Cruz had to respond. The attack was obviously going to take place so just as well get it out of the way now and the backblow has started for Rubio.
I am not saying this, and I don't support it, but I am relying what the Guy Bensons, the Steven Hayeses, the Jonah Goldbergs, the Rich Lowery---all of them have been saying. It is clear they hate Cruz, but are supporting him now because they hate Trump more.
