Maine is divided into 2 congressional districts, each represented by an elected member of the United States House of Representatives.
Unlike every other US State except for Nebraska, Maine apportions two of its Electoral College votes according to congressional district, making each district its own separate battleground in US presidential elections.
The districts are currently represented in the 113th United States Congress by 1 Republican and 1 Democrat.
