By Jim EllisMay 20, 2020 — The small state of Maine, with its two congressional districts, is going to attract a great deal of political attention between now and the election. Not only is the Pine Tree State one of the firewalls for Republican Senate majority hopes, the domain, one of two places that splits its electoral votes, will likely play a major role in determining the presidential election outcome, as well.
Maine and Nebraska divide their electoral votes such that the winning statewide candidate earns two electoral votes, while the victor in each congressional district is awarded one EV for as many districts as they carry. Maine, as mentioned, has two districts, and Nebraska three.
These districts came into play both in 2008 and 2016, when Barack Obama carried the 2nd District of Nebraska against John McCain in the former year, and Donald Trump took the 2nd District of Maine opposite Hillary Clinton in 2016. While neither CD became a factor in determining each of those elections, these CDs breaking differently than their state in a tight national election could result in the Electoral College ending in a tie.
The 48 other states and the District of Columbia use the winner-take-all system. Any state could divide their electoral votes like Maine and Nebraska, but those are the only two who choose the split vote method.
In the current presidential election scenarios, whether or not President Trump again carries ME-2 could determine if he is re-elected. Under one scenario, former vice president Joe Biden could win the national race even if he failed to carry Wisconsin so long as he takes the 2nd District of Maine and 2nd District of Nebraska. Doing so, along with winning the other swing states that touch a Great Lake, meaning Michigan and Pennsylvania, he would secure exactly 270 electoral votes, the bare minimum to claim national victory.
