John Fitzgerald Kennedy, often referred to by his initials JFK, was an American politician who served as the 35th president of the United States from 1961 until his assassination in 1963. He was the youngest person to assume the presidency by election and the youngest president at the end of his tenure.

The Democratic Party is one of two major contemporary political parties in the United States. Founded in 1828, it was predominantly built by Martin Van Buren, who assembled politicians in every state behind war hero Andrew Jackson, making it the world's oldest active political party. Its main political rival has been the Republican Party since the 1850s, with both parties being big tents of competing and often opposing viewpoints. Modern American liberalism — a variant of social liberalism — is the party's majority ideology. The party also has notable centrist, social democratic, and left-libertarian factions.

Massachusetts, officially the Commonwealth of Massachusetts, is the most populous state in the New England region of the Northeastern United States, exceeding 7 million residents at the 2020 United States census, its highest decennial count ever. The state borders the Atlantic Ocean and Gulf of Maine to its east, Connecticut and Rhode Island to its south, New Hampshire and Vermont to its north, and New York to its west. Massachusetts is the 6th smallest state by land area but is the 15th most populous state and the 3rd most densely populated, after New Jersey and Rhode Island. The state's capital and most populous city, as well as its cultural and financial center, is Boston. Massachusetts is also home to the urban core of Greater Boston, the largest metropolitan area in New England and a region profoundly influential upon American history, academia, and the research economy. Originally dependent on agriculture, fishing, and trade, Massachusetts was transformed into a manufacturing center during the Industrial Revolution. During the 20th century, Massachusetts's economy shifted from manufacturing to services. Modern Massachusetts is a global leader in biotechnology, engineering, higher education, finance, and maritime trade.

A Democrat from Texas, Johnson also served as a U.S. representative, U.S. senator and the Senate's majority leader. He holds the distinction of being one of the few presidents who served in all elected offices at the federal level.

In the United States Electoral College, a faithless elector is an elector who does not vote for the candidates for U.S. President and U.S. Vice President for whom the elector had pledged to vote, and instead votes for another person for one or both offices or abstains from voting. As part of United States presidential elections, each state selects the method by which its electors are to be selected, which in modern times has been based on a popular vote in most states, and generally requires its electors to have pledged to vote for the candidates of their party if appointed. A pledged elector is only considered a faithless elector by breaking their pledge; unpledged electors have no pledge to break. The consequences of an elector voting in a way inconsistent with their pledge vary from state to state.

He came to lead the conservative coalition in the Senate, and opposed President Franklin D. Roosevelt, largely blocking most liberal legislation after 1937. His son Harry Jr. succeeded him as U.S. Senator, but ran as an Independent following the decline of the Byrd Organization.
