I take it the same process will pertain as for this resignation a few days ago. Seems rather tit-for-tat that such a paired resignation would take place, no?

I was unaware that NY law directs the governor to hold a special election after a set number of days. Each state’s rules differ. You will be shocked, I’m sure, to learn that some governors will hold/delay special elections to benefit their party’s chances.
