Sorry it took so long to get back.
As per your most recent points, here are my disagreements:
1. Anyone running for political office, as far as I'm concerned, is a politician. If they weren't before, they are now.
2 and 3. I've got to assume that if the DA had any goods on other members of the staff, they'd have been prosecuted as well. Not only that, but, at least in my experience, whenever someone gets caught abusing public office, no one is angrier than the rank and file staff who view it as a smear on their own hard work - just as you view them here. I fully expect the new admin to tow a careful ethical line and especially if they are Dems.
4. It's no surprise that the people in office have been the ones involved in scandals, whereas the party out of power hasn't. That's sort of a tautology.
All that said, I imagine that you'll be happy when election day is done, because there's no doubt that the Dems took a beating over this.
