 William McGurn Wall Street JournalLet s get this straight. Calling Hillary Clinton a  bigot  has reporters asking every Republican in sight if Donald Trump has gone too far. But the Clinton campaign releases a video saying Mr. Trump is the candidate of the Ku Klux Klan, and it s all okey-dokey?Then again, Mr. Trump has already been likened to Hitler, Mussolini and Stalin. Small wonder there s a collective ho-hum when Democratic vice presidential nominee Tim Kaine says Mr. Trump is peddling  KKK values. This is what Democrats do. It didn t start with Mr. Trump, either. For years Democrats have portrayed the GOP as one giant hate group.Each presidential election, the drill goes like this: After Republicans nominate someone, he immediately finds himself having to prove he s not a hater   of African-Americans, of women, of gays, etc.This year Democrats added a twist.

The McCain campaign fired back, accusing Mr. Obama of playing the race card from the  bottom of the deck.  Funny thing: All those reporters always hearing  dog whistles  from Republicans somehow didn t hear this one.  In 2012, when Mitt Romney went to the NAACP and told them face-to-face about his opposition to ObamaCare, the stories were all about how he was really just trolling for the racist vote. Vice President Joe Biden put it more explicitly, telling a largely African-American audience that if Mr. Romney were to win, he d  put ya ll back in chains. The only difference today is that Republicans now have a nominee giving as good as he gets Continue article at The Wall Street JournalREAD MORE ELECTION NEWS AT: 21st Century Wire 2016 Files
