Not sure what you are talking about. Cruz has received criticism lately for his stands on the fast track trade deal — rightly so. No one even Cruz is immune from criticism if they take a stupid position like Cruz did. But that is just one issue and Cruz is a solid conservative. Is that what you mean?
I don’t think liberals are too worried about Cruz. It is not like he is the front runner.
True. I suspect they are the ones doing the big send up on on Rubio, because they have already published oppo research and plans to take him down.
