At least with Trump, all of his skeletons are out there. Lord knows what’s in the closets of the others.
Trump's vices seem pretty minor: he likes the ladies and a good time, and he used deferments to avoid serving in Vietnam (so did GOP establishment icon Dick Cheney, yet the people attacking Trump for this still think Cheney is some sort of hero with "gravitas").
It's the candidates who talk a lot about their moral purity who scare me. The moralizing and "righteous" high and mighty usually turn out to be the biggest crooks, hypocrites, perverts, and degenerates of the lot.
