As I wrote elsewhere, Trump won't lose support even if he doesn't bring jobs back from overseas, even if he continues to align himself with Wall Street and establishment types (which everyone with a working brain knew he was going to do), even if he leads an effort to privatize Social Security and Medicare, and even if he takes away Medicaid from a lot of people. His supporters, for the most part, will either blame Democrats or just ignore those things. Same with not destroying ISIS, not withdrawing from the Iran nuclear deal, not withdrawing from the Paris Agreement, etc.

The one deal-breaker would be if he made a reversal on civil rights (support of Black Lives Matter, support of LGBTQ rights, kicking out the likes of Bannon, etc.). That's the one thing Trump (and Republicans as a whole) simply cannot afford to do and won't do, because the Republican Party would collapse. Bigotry, particularly racism, is the tie that binds.

That there are so many Democrats who don't recognize that reality is heartbreaking.
