@snood,
Holder's racism is indeed a problem.
But I think the bigger issue is his opposition to the Second Amendment.
That said, we won't have to worry about a Democrat actually being elected until 2036 (and even then only if they purge their leftists and nominate a moderate). I'm sure Holder will be able to deliver a nice concession speech when Trump is reelected, and that is really all that the Democratic nominee is going to need to do this time around.
