A glossary of historical classifications of Democrats:
- Yellow Dogs: Term of diehard Democrats began in the 1928 election. Outraged that some Democrats were supporting Republican Herbert Hoover, Alabama Democrats rallied around the slogan: "I'd vote for a yellow dog if he ran on the Democratic ticket."
- Boll Weevils: Term used in the mid- and late-20th century to describe conservative Southern Democrats. Pejorative used by liberals in the 1980's to describe a bloc of largely conservative Southern Democrats who supported President Ronald Reagan.
- Blue Dogs: Descended from the Boll Weevils, group formed in 1995 when about thirty moderate to conservative House Democrats joined to counter the parties leftward leanings. Democrat and former Rep. Pete Geren of Texas said the party was being "choked blue" by liberals.
- Dixiecrat: A group of Southern Democrats who opposed racial integration and wanted to retain Jim Crow laws and racial segregation. After President Harry Truman's endorsement of the civil rights plank at the 1948 Democratic National Convention the Dixiecrat delegates walked out. Strom Thurmond, governor of South Carolina, helped organize them into a separate party.
