President Trump is not a Racist.
His narcissism transcends racism. It isn’t about anything but Donald Trump. If you worship him, he will try and get you what you want to keep the adoration coming, so he can continue to bask in the glow of it. He really doesn’t want to do anything but attend rallys and get his fix.
The racists worship him, so he can’t bring himself to criticize them and he promises them a useless wall. If it were Mexicans worshipping him, it would be open borders. OK not quite of course, since he and his agenda have largely been manipulated by sociopathic racists like Bannon and Miller.
