Many people who once were dupped by Cruz, woke up pretty fast, during this past primary season and only an extremely few here and in real life, are still in his cult. You are delusional in your assumptions re Cruz and his following. Not only that, but many who support Trump, now, would be far LESS inclined that way, should he pick Teddy...which I believe him to be too intelligent to do.
Teddy adds less than NOTHING to Trump; quite the contrary...he makes a Trump win less possible. Unlike his sychophants, most people loathe and abominate him, taken his measure and found him worse than "wanting"!
Who was president when you were born?
