There is an outside chance some of that would happen with President Trump. There is an absolute certainty just about all of that will happen, and more, with a President Hillary. Given Trump has carved out important positions that both parties have neglected for decades, and has shown both the will and ability to throw left-wing attacks right back in their faces, I'm will to take the obvious chance over the obvious cancer.

Sitting on a fork between Beastwoman and Trump, sure, go for Trump.
But if you are sincerely concerned about Trump's personality and fitness for office, you still have somewhere to go, which is Ted Cruz, as a reasonable alternative to succumbing to the Trump/Beastwoman fork.
The major risk with Cruz is that a) he might lose to Hillary (even with Trump according to polls, on that score), and b) even if he gets elected, there is so much GOP-E resentment toward him in DC that he wouldn't be able to charm birds to poop on him, much less get the GOP cauci to cooperate with him. (Again, conceivably equally true of insurgent Trump.)
You're not stuck with a Trump/Beastie dichotomy. If anyone other than Trump can win the nomination, it would be Cruz. And Cruz has so far outpolled or polled even with Trump in a head-up election opposite Hillary.
