Is there any short guide for outsiders as to what's going on with the New York Senate drama?

Seems like an almost absurd situation. Is there any short, comprehensible guide or explanation as to what’s going on in this drama?

I suspect that the honest answer sounds like one of the snarky MPSIMS-thread answers: “No.” However, I too will look forward to seeing what people advance as relatively short and clear explanations of the contretemps.
