How does Trumps vulgar remarks stack up against Clinton's failure to protect the lives at Bengazi. Or against her email recklessness that very likely puts people in jeopardy, or accepting millions of dollars from Arab nations who do far more than talk badly against women. They kill them. In so called honor killings. 
What Trump said is terrible. But as terrible as it was it is nothing compared to the real physical harm and destabilizing environment caused and created by Clinton. I think that many of the politicians claiming to longer support Trump will, as millions and millions, and while in the privacy of a voting booth, vote for trump.
