Pro-Clinton #HillarySoQualified hashtag backfires

A hashtagmeant to talk up Hillary Clinton's qualifications for the U.S. presidency quickly went sideways, resulting in alate-night Twitter fight between her supporters and those of Bernie Sanders.

#HillarySoQualifiedwas created by backers of Clinton after Sanders responded to a new round of attacks from Clintonat a rally in Philadelphia.

"She has been saying lately that she thinks I am quote-unquote not qualified to be president,"Sanders said.

Clinton had questioned Sanders'qualifications as a bone fide Democrat and for the presidency earlier in the day, but stopped short of saying he was notqualified.

"Let me just say in response to Secretary Clinton, I don't believe that she is qualified if she is through her super PAC taking tens of millions of dollars in special-interest money," Sanders said.

"I don't think you are qualified if you have voted for the disastrous war in Iraq,"he continued, referring to Clinton's 2002 vote as a U.S. senator.

Kim Frederick, a Clinton supporter in Houston, said she was "livid" at the remarks of the Vermont senator.

"Just beyond fiercely angry about this, and I could barely control myself," she said in an interview with the Washington Post.

So, started a hashtag and posted some well-worn memesabout Sanders' accomplishments.

Other Clinton backers picked up on the hashtag, which eventually becamethe top worldwide hashtagWednesday evening.

However, Bernie boosters, noted for their social media acumen, then picked up on #HillarySoQualified, usingit ironically and posting well into the wee hours.

By the morning, more than 170,000 tweets had been posted using the hashtag.
