Absentee voting in Maine is getting underway, with the state's four Electoral College votes up for grabs and a number of other national, statewide and local races on the ballot.

Maine is one of two states in the U.S. — the other is Nebraska — that does not use a winner-take-all system for all its electors. In the presidential race, two electors are given to the winner of the statewide popular vote, while one elector is awarded to Maine's District 1 and District 2, respectively.

Maine is mostly Democratic, but its vast 2nd District is critical for a Trump victory

Maine is one of several Democratic-leaning northeastern states. President Biden won here by about nine points in 2020, improving on Hillary Clinton’s margin four years earlier. And it hasn’t voted for a Republican at the statewide level since 1988. It is ranked Likely D on the Fox News Power Rankings.

Like Nebraska, it also allocates its electoral votes by congressional district. The winner of the statewide tally receives two votes, with another vote for the winner of the presidential tally in each of its two districts.

The small coastal 1st District is solid blue territory. The 2nd District, which is predominantly rural and represents almost all the land area of the state, leans conservative.

Trump won the 2nd District by 7.4 points in his last race, and it’s ranked Likely R this cycle. The former president will look for a win here to get one step closer to the 270 electoral votes he needs to win the presidency.

The same district is also home to a competitive House race.

Maine’s 2nd District: Incumbent Rep. Jared Golden is one of five Democrats running in districts Trump won in the last presidential election (Golden won by 6 points). The former Marine made headlines this year when he said he "didn’t know" whether he would vote for Biden again and was one of the first Democrats to question Biden's mental fitness. This time, he’s up against Maine State Representative and former NASCAR driver Austin Theriault, who says he wants "more balance and less extremism" in politics. This race is a Power Rankings toss-up.
