I'm not entirely convinced that the alt-right isn't a boogeyman. Not sure what the KKK or the Nazis have to do with anything.

Trump has courted the white supremacist vote.

In fact, he was just officially endorsed by the KKK's official newspaper... his whopping 2nd newspaper endorsement!

Not really interested in why the KKK supports Trump, very interested in why almost half of voters do.

Why the KKK supports Trump is rather telling about what Trump stands for, as is the fact that he has retweeted numerous white supremacists. It's not exactly that it's a one-way street where he can't help that they vote for him; he likes them, courts, them, retweets them, and has never distanced himself from them.

Trump? Or his campaign? Some people in his campaign have a tendency of denying everything he says. If it's Trump, it would be a first. He tends to waffle around it and give non-answers, because he doesn't want to drop his allies, but doesn't want to be seen supporting either.

They are very real. Check out the Daily Stormer if you don't believe me.

Drumpf is supported by David Duke, the KKK and legions of neo-Nazis.
