Outside NYC, Westchester swung even more towards the Democrats. Being the "home base" of the Clintons probably helped. And Trump was likely a bad fit for the county.

In Nassau, the GOP vote stayed more or less the same. Maybe there was a swing towards Trump on the South Shore offsetting a D swing on the North Shore? Trump is also a better fit there given that it's more insular and "New Yawk" and the white population isn't as educated as Westchester.

(Someone once explained to me that people who are wealthy and care about prestige prefer Westchester, those that are wealthy and don't prefer Nassau).
