Maine and NH could both go to split control this year. NH is less likely to do so than Maine though.
I don't think it will have any impact on who wins there, though, unlike in some other states.
Maine has a 2/3 vote requirement to pass a redistricting plan, although for congressional and county commissioner redistricting that requirement is statutory and can be "notwithstood" or even repealed by legislation adopting a plan. The Democrats considered doing that in 2003 but feared the Republicans would withdraw support from the concensus State House redistricting plan if they did, so they let the Maine Supreme Judicial Court draw the lines.
I remember reading (and hearing on a New Hampshire radio debate on a constitutional amendment "reauthorizing" and regulating the use of floterial districts) that redistricting broke down on party lines in 2001/2 and 2003/4 (the courts drew a State House plan in 2001/2 and the Republican Legislature passed and presumably the then-Republican Governor signed a law adopting another plan in 2003/4; Democratic Governor Jeanne Shaheen (sp?) had a veto in 2001/2). Like Maine, however, New Hampshire has only two congressional districts and a history of modest changes in the lines (goving back much further than Maine, perhaps in part because it has had only two U.S. House seats for much longer) so control of state government might not matter so much in terms of congressional redistricting. I think legislative redistricting in New Hampshire is a different story.
