Like the rest of Maine, Cumberland County was a solid Republican county after the Civil War. Between 1860 and 1960, the Republican presidential nominee won Cumberland County in every election except 1912, when the county was won by Democrat Woodrow Wilson following a split in the Republican vote between incumbent president William Howard Taft and Progressive nominee, the former Republican president Theodore Roosevelt. The county remained steadfastly and overwhelmingly Republican even in Franklin D. Roosevelt's huge Democratic landslide win in 1936.
In 1964, Democrat Lyndon B. Johnson won Cumberland County and Maine's 15 other counties as part of a 44-state landslide over controversial Republican nominee Barry Goldwater. Cumberland remained in the Democratic column in 1968, backing Hubert H. Humphrey, who had chosen Maine Senator Edmund Muskie as his running mate. These Democratic victories were a sign of things to come for Cumberland County. Though it would snap back into the Republican column for Richard Nixon in 1972, Republican victories in Cumberland grew increasingly narrower, with Republican Gerald Ford winning it by less than 2,000 votes over Democrat Jimmy Carter in 1976. Carter would narrowly win the county in 1980, marking the first time Cumberland had diverged from the rest of Maine in a presidential election, as the state would be carried by Republican nominee Ronald Reagan.
Reagan would easily carry Cumberland in his 49-state landslide re-election in 1984; however, it was Maine's closest county, with Democrat Walter Mondale losing it by a relatively narrow 13.7%. In 1988, George H. W. Bush would become the last Republican, as of 2020, to carry Cumberland County at the presidential level, winning it by less than seven points. In 1992, Democrat Bill Clinton would win the county with nearly 43% of the vote against Bush and independent Ross Perot; it would be the last time a Democrat would receive less than 50% of the vote in Cumberland County in a presidential election. In 2004, Cumberland would become the most Democratic county in Maine, a position it has retained through 2020. In 2008, over 105,000 ballots would be cast for the Democratic candidate, Barack Obama; it would be the first time a candidate received 100,000 votes in Cumberland County in history. Democrats have exceeded 100,000 votes in Cumberland in each subsequent presidential election. In 2020, Democrat Joe Biden won Cumberland County with 66% of the vote, the most lopsided presidential election result in the county since Lyndon Johnson won 69% of the vote in 1964.
In 2012, the county voted 65% to legalize same-sex marriage.[9]
