Don't know how accurate, but on the politics sub they're saying numbers are higher than they have been in many years but not by much and more split out between a bunch of different candidates rather than the usual top 2 or so getting the bulk of the votes.

Bernie for example won NH in 2016 as well but back then he got more than twice the votes, just with so many other candidates getting an OK amount of votes themselves the overall numbers are up a bit
