50 of the 60 years since WW2, NYC has been run by Democrats.Meaning it's been "not Democrats" for 10 of the last 60. (Probably meaning Republicans, but I don't want to assume.)
16 of the last 30Meaning 14 of the last 30.
So New York has been run by someone other than Democrats for 10 of the last 60 years, including 14 of the last 30.
Okay.
