Any kind of Trump endorsement would be the end of his career
I don't know if I would go that far.
I don't believe it would be a career stopper.
He'll probably dance around it, supporting "all" republicans to stop the democrats, etc., without specifically mentioning Trump by name.
But who knows, I've been wrong before, and reserve the right to be so again!
In a video released afterward, Cruz said "we didn't talk about endorsements", so, it sounds like he is still playing it cool.
