I never understood the fuss, but I guess that's because I didn't watch many news conferences. As somebody else mentioned, Cuomo was rather disliked before COVID-19.
My lasting impression is of Gov. Cuomo and Mayor de Blasio swinging their dicks in a measuring contest over who had the power to shut down NYC. De Blasio took much of the blame for inaction, but the governor of NYS has sole authority over lockdowns. This was when NYC had by far the most severe outbreak in America, and CA and WA issued lockdown orders before New York did...
As for the accusation, the accuser alleges Cuomo repeatedly said whatever he said and that it was witnessed and she wasn't the only target. If all of that is true, then unlike with the GOP, Cuomo isn't getting any job promotions.
