National Progressive Party (TNO: A New Frontier)

The National Progressive Party is one of three major parties in the United States, along with its contemporaries the American Liberal Party, and its historic rival the Democratic Party. It was founded in 1958 in preparation for the 1960 presidential election.

From its creation until the late 1960s, the party was a big-tent anti-establishment party, created to oppose the political duopoly established by the merger of the Republican and Democratic Parties. Its initial members were made of southern Dixiecrats, northern Conservatives, Progressives, and Leftists. During the popular Kennedy and Harrington administrations the party began to coalesce around the "Center" wing, at the time made of Progressives and a few Democratic Socialists. Dixiecrat and Conservative members of the party began to be primaried, defeated, or would defect to the Democratic Party.
