The latest in Maine

Sept. 29, 2021

Maine Gov. Janet Mills signed a new congressional map into law on Sept. 29, after a supermajority passed it in the state legislature. The approved map was a compromise put forward by the state’s apportionment commission after each party had initially proposed separate congressional maps.

The new map is not a dramatic departure from last decade’s map, but since Maine’s population growth has primarily come from the 1st District, some voters had to be moved from the Democratic-leaning 1st to the Republican-leaning 2nd in order to equalize the populations of the two districts.

The approved plan moves the state capital, Augusta, into the 2nd District. As a result, it marginally helps shore up support for Democratic Rep. Jared Golden, who represents the seat despite former President Donald Trump having won the district in both 2016 and 2020. Golden is one of only seven Democrats who represents a seat that Trump won in 2020, currently giving Democrats control of both of Maine’s two congressional districts. That seat is sure to be hotly contested in the 2022 midterm elections.

Our latest coverage

Who controls redistricting in Maine in 2021?
Neither party fully controls the congressional redistricting process. New maps are drawn by a bipartisan commission made up of state legislators and citizens, but the Democratic state legislature can modify or reject the commission's proposals. The final map must be passed by two-thirds of each chamber and signed into law by the Democratic governor.
