I live in New York, although not in NYC. I call elections “affirmations”, as there are never meaningfully contested general elections, and probably a meaningfully contested primary about 1/3 of the time. All of the bigger offices (mayor, county exec, Congress) attract enough money that the incumbent can find an African American or other bloc voter candidate to run on a third party line and split the opposition vote. State legislative offices are only involuntarily vacated by death or felony conviction.
It’s difficult to envision a brighter future as the national GOP platform is so poisonous.
