Yes, it is slightly possible that the Left thinks he is a pig who needs to go on the merits, but we know the Left doesn't care for things like that.

For a long while, I had thought he was too big of an uncontrollable force in the national Dem power structure and they needed to coalesce behind Biden/Harris. In other words, there is no room for anyone longing for Cuomo to lead the Party when Biden is removed for dementia. So they had to destroy him.

Of course it is true that his national profile among Dems and the media was a looming embarrassment given his scandals, and of course they had to find something to distract from the nursing home murders ... especially since it leads to questions about 4 other Dem Governors.

I think elements of 2 and 3 are correct, but I'm now noticing that his scandals have weakened him so much that he can't effectively be a cheerleader for New York's efforts to prosecute Trump under NY laws. And that's clearly where they were headed. It would look like political desperation if Cuomo talked about pursuing Trump now, so they are left without a rock star to lead that charge on every CNN and MSNBC program ad nauseum. So they need to replace him with someone who can put the focus back on Trump and NY's prosecution of him.
