Or have the reverse effect.
The Democrat base wasn't as enthused about Hillary as they were told they were, so many didn't see the need to waste time voting for some lesser of... who was supposed to be a sure win. Add the Comey announcement, long lines for voting, problems with some polling booths, etc, and many skipped it.
The DNC and Hillary screwed themselves royally. Seems Hillary hasn't got a clue what losing twice means, and with 2020 looking to be graced by her striking inability to get the hint and shut up and go away, no surprises as to what those results will be...
