I'm sympathetic to that way of thinking, but it's just not how we handle sex crime allegations against politicians in this country.
If it was Bernie he'd be demanding a resignation.
When something like this happens I tend to think of it from two perspectives:
First: how will it affect policy and the balance of political power?
Cuomo is an abatross around the neck of the Democratic Party and he's likely going to fall sooner than later.
His lieutenant governor is also a Democrat (and a woman), and while I haven't done any real research on her it's hard to imagine she'd be as bad as he's been for the last five months.
Cuomo has put me and my family in real mortal danger so there's almost no risk for me in losing him as governor.
Second: what treatment does our society expect high-ranking politicians accused of sex crimes to get, and how will the treatment of this specific accused politician affect that expectation going forward?
Frankly, we have a major problem with politicians getting away with literally anything and the more people we make examples of (as long as it doesn't hurt our policy goals), the better.
Politicians are not civilians, and I have yet to meet one that deserves the pity and empathy that you'd give to an average person. They should not have an inherent presumption of innocence, because we know they live and work within an extremely corrupt system and their accusers quite literally risk their lives to make these claims. They will be threatened and harassed, and face retaliation in some form.
