NYC has kind of a lot of influence on the country as a whole though. At a minimum, the NYSE is kind of a big ◊◊◊◊◊◊◊ deal, NYC has the largest regional economy in the world - larger than most other whole countries, and the UN is headquartered there. While mayor may not be the single most important role in the US, it's not like it's insignificant to the health and welfare of the city.
I'll make you a deal: You agree that nobody outside of the US should give a crap about who the US president is, and should just shut up about it, and I'll agree that NCY Mayor is totally a non-issue that nobody outside of the city should care about.
