Yep. And he's hurting himself at this point. How long the people remember is to be determined. I can picture a range of how this plays out, from "minor damage" to "Titanic."
-- Whether he realizes it or not, he is running for VP or scotus. And he has probably scuttled both of those opportunities as well. --
SCOTUS is a good place for misfits. He has a chance at that, although the dysfunctional Senate could, by will of 41 DEMs, prevent him from being appointed.
For scotus, it would come down to political capital and how much President Trump would want to use to get Cruz through. Precious liittle at this point I fear.
Which gets back to how long those memories are, and Cruz was/is an equal opportunity irritation.
