What was the context of why the forum disliked him c. 2015?
I wasn't around till April 2015 here and didn't follow NY politics much at the time. My guess is Mr. Cuomo cutting healthcare and other social services and disbanding his own corruption board after various of his staffers faced legal trouble. He also cooperated with the IDC at the time that de facto gave the state senate to the GOP and approved a R-friendly district map following the 2010 census. In all likelyhood, political folks here also (correctly) concluded he was a corrupt machine politician and a bully.
