Here, I'll propose this for you as a perceived Rapeyness scale.
Imagine that you have an attractive, adult daughter, who's informed you that she's been invited to said candidate's room later, alone, to discuss some political matter. On a scale running from Elton John to Bill Cosby, how worried are you that something bad could happen to her?
I'd trust Bill Clinton more than I'd trust Donald Trump. I'd trust George Bush (Jr and Sr) more than I'd trust Bill Clinton. I'd trust Bernie Sanders more than either of the George Bushes.
Donald Trump is no Bill Cosby, but he's still pretty bad imo.
