The Senate flipped from a 14–10 Democrat majority to a 14–10 Republican majority, the 400-seat House that had 157 Republicans will now have 213, and Republicans have taken control of the powerful Executive Council, 4–1. The Executive Council, unique to the Granite State, appoints government officials, controls the release of money from Treasury, and can make pardons.
I hope the lesson people take from all this is that State and Local elections matter.
