I think its a political issue, but I see it from a different angle.
It’s no secret Cuomo had Presidential ambitions. It’s also no secret that there are power cliques within the Democratic Party.
Letitia James is a very political animal. Just look at how hard she’s worked to use the legal system against Trump. I’ve also read that she has ambitions to primary Cuomo in the next NY governor’s elections cycle, and is favored by the Obama wing of the Dem Party.
So, it’s not surprising that she would support one of those famously impartial investigations her office is known for. I’m sure Cuomo is a slobbering, ass-pinching jerk, and a nursing home murderer, but I think the reason this harassment investigation has been promoted so hard has to do with the ambitions of Letitia and others who would like to take Cuomo’s place in the power hierarchy.
That is an interesting, and compelling, theory.
