Trump's voter appeal lies in the alternative

Was recently in a debate with a left-leaning friend who said he was sad at what the republican party had become when it nominates a guy who calls immigrants murderers and criminals. This was my reply:

Not literally all immigrants, that's not fair, but there are countless victims of crimes that, but for America's immigration control system, the most lax or non-existent in the world, would not have happened.

Either you advocate throwing open the gates entirely and letting every third-world dreg who wants to come here in, or you see the value in controlling who comes in and who doesn't.....the same as every other country on Earth.

I'm quite sure Trump, as all conservatives/libertarians have stated countless times, would favor fast-tracking the educated, productive classes of immigrants who're waiting patiently and lawfully in line for years, rather than holding them up while those willing to commit a crime stroll in whenever they feel like it, depressing wages and straining the absurdly generous welfare apparatus.

 What's going to be sad is the state of the union when, as Tim Caine promised, 15-20 million illegal aliens receive amnesty and shortly thereafter I predict, full voting rights. Within a decade, democrats will never lose another national election. Who seriously wants 9 RBG's on the Supreme Court? Or Nancy Pelosi's and Harry Reid's controlling both houses of congress and every agency, with literally no check or balance on anything?

That's a pretty grim picture if you ask me and that's why people are rolling their eyes when Trump says something insensitive or hurtful, but are still not voting for Hillary.
