It's like this sub-group of working class people (many are, of course, NON-white and most of them didn't vote for Trump- so this is more "white" than "working class" are fine with him reversing most of the labor gains of the 20th C-- worker protection, employer liability, employment opportunity, organizing unions....
I used to live in West Virginia, back when the coalmines ruled and could pollute every inch of that beautiful state, cause floods and ruin the rivers.
They voted madly for Trump, who wants to return that very state to the polluted condition of the past.
Why? I mean, I get why my rich investment broker friend votes for whoever is the GOP candidate. He thinks that he'll make more money under a GOP "business-friendly" president (though, of course, the markets almost always do much better under a Democrat).
And "standard GOP voters make up most of Trump voters (and Romney's etc). But these others-- why do they vote to deprive themselves of safety? I really think they are so consumed with resentment, they'd almost rather die than have someone they resent in charge. (I don't know why they don't resent the born-rich, worker-cheating Trump.)
