In our deep-state era, I believe pretty much every higher level politician is deeply corrupted and compromised.
The cynic in me thinks then that we are viewing the fallout from a larger factional battle, and whatever faction Cuomo belongs to (Clinton?) is on the decline, and now that “election” is over, its time to take out one of their capos.
It is why the mob or gangs make committing a really bad crime (murder) as the initiation rite. So if the new member ever decides to not do what they are asked, that Sword of Damocles is always out there to keep them in line, OR ELSE.
