The districts are so tiny, coupled with all the turnover in recent elections most people probably have no idea who their state Rep is.
The majority voted RAT for everything else so why not State House?
the districts are not that small because each town has multiple house reps. Some towns are in multiple different districts which have multiple reps.
Of course, if there were 500 districts, they would be small. But if that small some would not be able to find candidates. I know one very small town that has 2 reps in one district and also is in a different district with 2 other reps.
I do not know why NH swung so wildly to the DEMS. The ronPaul peeples maybe did not like MITT. NH is so less interesting with the RINOs a majority control over a minority party. Blaming the Mass-immigrants ... the rural northern counties also are trending RAT.
