Let's parse this a bit, shall we?
"He had an affair with a subordinate." An "affair" means more than one time, and by mutual consent, i.e., the lady was ready,willing and able.
He "contributed to an atmosphere where sexual harassment was permissible". He contributed. No where does it say he established and singularly maintained said atmosphere. And just how, specifically, did he contribute? That being the case didn't she likewise contribute to said atmosphere? She is libel to official prosecution?
Politics is a smash mouth game. It's therefore pretty much a given this is guy has political enemies. Does this gal factor in? If so, how? To what degree? Would her past [viz. office politics] stand up to similar investigation(s) as his? Which is the closer category for her: Anita Hill or Ellie Mae Clampett?
Frankly this sounds like a hatchet job on this poor SOB. I'm not defending him in the least, but like I said before politics is smash mouth game.
Marc Dann deserves all he is getting. He has a track record of incompetence in running his office.
The Dems in his own party are calling for his impeachment, not for anything he has done, but because it will cause political problems for themselves (first) and their party (second).
The Republicans want it both ways. They want to rail on him now by calling for him to leave office, but they also want Dann to remain in office so they can use him against others in November's election.
The issue is not Dann & his affair.
It's the people he's hired & what they've tried to get away with - sex harrassment, wrecking state autos while probably drunk & not reporting the damage, trying to torpedo investigations, etc, etc.
The affair is the icing on the cake.
