Could be super, super anecdotal -- and perhaps too much information to share online -- but Fargo has Microsoft's second biggest campus in the US. When I worked there, I'd say half the campus was from out of state (including myself): people from Texas, Seattle, Boston, New York, etc. I wouldn't be surprised if a lot of these more "liberal" transplants who now live in Fargo are waking up a bit now that they're out of their bubbles. I certainly did, and lots of others did, too. Probably doesn't fully explain why these people want to change their vote all of a sudden, but just thought I'd share a bit of my experience in the state.
