Ted Cruz is just as psychologically beat up as WE are and though he's "a politician", he's still a man with a family.
Ted Cruz will come back because the leftist public demands it and will accomplish nothing tangible for the state of Texas.
It's out of Ted Cruz's hands
From what I read here, I doubt that the leftists are going to be the hardest on Cruz. Besides, since they would never vote for him in the first place, they will have little influence on whether he does or does not survive politically. Also, does he have 2, 4, or 6 years left to be served before his next election?
