Texas can have Cruz as their Senator as long as they wish. (Cornyn too)
Conservatives will have to decide if they love the Constitution more than they love Ted Cruz if he runs for President again.

Perhaps I am wrong, but I do not see the GOP base selecting a senator for the presidential candidate in the foreseeable future. We’ll let the Dems stick with that paradigm.
