Those of Cruz’ supporters who are conservative will do anything and everything they can to prevent a Queen Hillary reign/final nail in the coffin of the US. They’ll need no external motivation for that; they’ll do it simply for love of country.

In the interest of full disclosure, I've already committed to supporting Trump -- ever since he passed 1237 delegates. But the ugly, lingering Cruzophobia on this forum is going to turn away more Cruz supporters than it's going to attract.
