Pandering to racists since the start:
* Initial refusal to rebuke David Duke.
* "Rapists" remark.
* Violence on "both sides".
* Not mentioning the Jews on Holocaust Remembrance day.
* No traditional White House Ramadan celebration.
* Attacking the hispanic judge in the Trump U case because of their race.
* Calling for and attempting to implement a "Muslim Ban".
* Appointing Jeff Sessions, who had been denied a judgeship due to his racist beliefs.
* The dog whistling about the lawless "inner cities".
* Supporting the birther theory.
The list goes on and on.
Even when he does rebuke racists, it's never prompt, and always with a wink and a nod. If you don't believe me, go peruse stormfront and look at all the threads celebrating their "victory" when Trump says these things, they recognize what's going on.
