I'd like to see something more like this, but if they havent done it by now, idk if they ever will. This all but guarantees a 1-1 party split
I think the reason we never see something like this is because it basically divides the state into "Rich New Hampshire" and "Poor New Hampshire". The representatives from either party probably don't like the NH-2 district.
I know in a lot of Ann Kuster's rallies she frequently toutes all the developments in Nashua/Salem as part of her record. She probably doesn't want to lose those urbans areas in the south.
