The mayor of NYC in particular is powerful because of the financial sector and the influence they can have on the people living in the financial capital of the world.
The mayor is like a mini president over the specific city, the governor can override the mayor. For example if the governor wants national guard the mayor can't do shit. He can only say "NYPD, don't help," but it's not like they do anything anyway so it's a non-statement.
The power of the NYC mayor is being the executive representative of that financial economic sector to the US Federal gov.
