-ME and CT need 2/3s majorities. Practically this means little change, though such change probably benefits the party in power like 2010 where the minuscule changes in ME benefited pubs, and CT dems.
The 2/3 requirement was only in statute for congressional redistricting in 2011 (it was in the Maine Constitution for legislative redistricting, and since 2011 has been in the Maine Constitution for congressional and county commissioner redistricting as well), so Republicans had more leverage in 2011 with their trifecta then Democrats will have in 2021 even if they keep their trifecta in 2020 (likely) but fail to win 2/3 majorities in both chambers (also likely (that they will fail in that)). The threat of a People's Veto was cited by one Republican who was on the 2011 advisory commission as a rationale for abandoning their east-west plan and offering up one that made smaller changes but still helped them in CD-2, although he pointed out that the Republicans had offered up that plan earlier and had it rejected so "if anyone caved, it was the Democrats."
I'm fine with light (Atlas) red for Maine instead of green. Just know that it's a lighter shade of Atlas red then the Atlas blue would have been for Maine in 2011.
