Buttigieg trailing Bernie by only 4% in NH is another win for him. I expected something like a 8-12% margin, especially given Bernie's performance in the same state in 2016.
Klobuchar is an obvious winner, she went from "should drop out" to viable campaign. The results are mostly good, but some bad for Bernie. Good in that going into Super Tuesday there are at least three serious moderates splitting votes and Biden still lingering. The bad....three (four if you count Biden) moderates are splitting votes and he isn't generating the separation you'd expect in that scenario. The exit info on tonight is going to be interesting.
