I would have thought the same...but the Dems are really that stupid and delusional. They think the media will just prop him up and make him look good or that so many people are going to hate Trump so much he will just sit there and coast to victory without having to do much.

Shrillary has never been well-liked even within her party especially by the Bernie bro wing - a sizable voting bloc. Mooch, despite media turd polishing, is not well liked either and has not made a name for herself outside her leftist bubble with voters the dems need to win. Cuomo probably did the political calculus and would rather square off against Pence next cycle. Why jump in late and just be a footnote in history as the losing candidate?
