There was apparently a big push by the Democrats to get people with weekend homes upstate who otherwise reside in NYC to change their voter registration to their upstate residences to push those areas left. I'm guessing this is a big part of the story.
Interesting. I thought Ulster county which usually goes Democrat is where a lot of New Yorkers move to and thus why it is more liberal, but didn't realize Columbia County is as well. Perhaps also get some Boston residents too as almost equal distant between NYC and Boston.
