Where is your proof regarding that claim? I'm talking legitimate, irrefutable evidence, not bullshit from White House drones or talking heads on Faux News.
Of course Trump would understand the problem about illegal immigration, after all, he has, or rather HAD illegals working at his golf resorts for years. As for calling Trump sane, that's high level nonsense.
If you mean those voters fell for Trump's empty promises, none of which he's followed through on, well, that's THEIR problem, isn't it?
Yeah, just like the dopes who support him. To quote a line from a popular sci-fi movie: "Who's the more foolish? The fool, or the fool who follows him?"
