Funny how Trump's critics seem determined to ignore the fact that McCain started the exchange by calling Trump's supporters "crazies." Trump held a rally in Arizona and 15,000 people showed up. McCain called them "crazies."
Gee, what's "crazy" about them? That they want a balanced budget, good trade deals--ones that help us, a better economy, a secure border (something that McCain has given lip service to for years)? That they want illegals who have serious committed crimes to be jailed or deported? That they want so-called "sanctuary cities" to stop harboring illegals and to obey the law? That they want our vets property taken care of? That they want the military to be made stronger, not weakened to historic levels? All of these are Trump positions. What's "crazy" about them?
