Mamdani looks like he wins easily.
Sliwa has no chance of winning and was never a serious candidate. Republicans screwed up by letting him the primary unopposed. They should have anticipated Mamdani winning the Democrat primary and fielded a serious candidate.
Some people say Cuomo is running to throw the election to Mamdani. Cuomo won't get enough votes to win, but he is getting enough votes to prevent Sliwa or anyone else from winning. With Cuomo in the race as an independent, that prevented a stronger anti-Mamdani candidate from getting traction.
There is no runoff or ranked choice in the NYC general election. Mamdani will win with 40%-45% of the vote, with Silwa taking just enough votes from Cuomo to throw the election to Mamdani.
Even though it sounds nice when campaigning, Mamdani won't be able to implement most of his plan. A lot of his proposals require approval of the NY state legislature, such as tax hikes and rent freezes.
Since I live in NYC, I'm hoping it isn't a total disaster.
Even if Mamdani loses, NYC has a steadily growing Muslim population. Even if Mamdani loses, 4 years from now, NYC will have even more Muslims. Some Muslim will get elected mayor eventually. At some point, there will be a Muslim mayor than can win without pandering to the left and the commies.
