How many times and in how many different ways do Trump/Pence have to disown and disavow David Duke and his ilk?
You and the establishment media just don't get it. You and they aren't helping Hillary with this kind of thing---you're helping Trump.
Here's why: contrary to your narrative, the vast majority of Trump supporters aren't racist, xenophobic or whatever ridiculous adjectives are in vogue now. And beyond that, they are sick of being condescended to by liberals on race or the plethora of other ridiculous -phobias the left obsesses over.
Here is what that translates into: not only are you solidifying Trump's base, you risk losing independents who 'get it' about all the above. Some of them may not even care for Trump but they can't stomach the constant hypocrisy from a media that is so totally in the tank for Hillary---they will stoop to such low-ball and deplorable political tactics in order to keep her campaign afloat.
So please keep it up.
