For some strange reason, people keep expecting Donald Trump to turn on his base. Trump has no support from the press, has alienated mainstream Republicans by firing Reince Priebus and has insulted the Republican leaders of Congress. He has even flamed members of his own cabinet. The only meaningful support that Trump has left is his base.
Why would he ever do anything to upset these supporters? They are primarily white, so Trump will never rush to condemn ‘white rights’ advocates. They are primary middle class and traditionally valued, so Trump will never go our of his way to support gay rights, immigration, etc. Whether or not Trump agrees with them, it just smart politics not to piss off your supporters.
The exception is when the condemnation of Trump gets so intense that he has to do something, like the situation with the white supremacist murder-by-car recently. Trump finally issued a condemnation, but his supporters know that he did it only under extreme pressure and as part of playing the game.
It kind of makes one nostalgic for George W. Bush. At least he had principles. Trump will embrace whatever keeps him in power, even if it is the KKK.
