進歩党
The 1948 Progressive Party is only tenuously connected to the original Progressive Party (1912–1932). Members of the 1948 Progressive Party, however, have joined the later state Progressive Parties, thus linking the 1948-1960s group to the Vermont Progressive Party, Wisconsin Progressive Party, Minnesota Progressive Party, California Progressive Party, Oregon Progressive Party, and Washington Progressive Party, as well as the Citizens Party of the 1980s and 90s.
