Maine State Senate: Democrats needed to flip three seats to gain control of the chamber. The potential for that to happen existed largely due to term limits - 13 of 35 incumbents (37%) were retiring or running for a higher office in 2012.
Maine House of Representatives: 52 (34%) of incumbents retired, most due to term limits. Democrats needed to gain four seats to get control of the chamber.
The Democratic Legislative Campaign Committee identified five races that they would target and assist in funding so that Democrats can retake both chambers, including House districts 128 and 139, as well as Senate districts 17, 25, and 32. The DLCC is primary financed by labor unions.
- District 3: Term-limited State Rep. John Tuttle (D) defeated Bradford Littlefield (R) for this open seat.
- District 27: State Rep. Herbert Clark (D) was defeated by incumbent Senator Douglas Thomas (R). Clark claimed that Thomas was "in hot water in his district" due to an unpopular proposed highway project that passes through the district.
- Assistant Democratic Leader Teresea Hayes defeated Republican challenger Timothy Turner. Hayes narrowly kept her seat in 2010, escaping with a 2,122 - 2,012 over Ryan Lorrain.
- District 128: Republican Heather Sirocki faced a stiff challenge from Jean-Marie Caterina (D), but survived unscathed.
- District 139: In a rematch from 2010, Joseph Wagner (D) was defeated by incumbent Aaron Libby (R).
