Well, I don't disagree with you (completely), but (a) those scandals don't represent all of our politicians, even the ones in Washington! and (b) they were discovered because at least some people still had enough of a moral compass to believe that those actions were in fact a problem (both legally and morally); (c) we should have higher standards, as opposed to tolerating what some people do, whatever the reason for said toleration; (d) neither candidate may have had the moral high ground, but that doesn't mean then that either one of them should get a free pass on bad behavior; (e) even if one were inclined to dismiss what DT Jr. had done "in the heat of an election," his subsequent waffling post-election, as well as JK's lying about it on his security clearance paperwork is still a problem - a big problem, in my eyes. 

As for the superfund, well, yes, I would agree with you, though despite my moral outrage, I don't think character is the main issue. I think the problem is money.
