Is there something special about the rules of the road in drawing Maine CD's?
It's a bipartisan "advisory" commission that draws the lines; the legislature isn't required to follow the map they draw but I'm not sure in practice if that ever happens.
So the maps the parties drew their respective maps to lobby the advisory commission?
I'm posting on my phone right now so I can't check, but I assume those maps are the official proposals of the respective parties on the board (for the record, the 15 member board consists of both state party chairmen, five legislators from each party, a private citizen selected by both parties, and a third citizen selected by the two other citizens).
