Caucus

Voting

Nobody is quite sure where the word comes from. The best guess traces it to a Native American word for counsel, picked up in colonial Boston.


A caucus is a meeting of members of a party or faction to pick candidates or set strategy. In presidential primaries, caucus states gather voters in rooms to debate and group themselves by candidate, rather than casting private ballots.

The word is distinctly American, appearing in Boston by the 1760s. John Adams mentioned a Caucus Club in his diary in 1763, where, he wrote, party business was settled and candidates chosen before the public ever voted.

Its origin is a genuine mystery. The most cited theory traces it to an Algonquian word, often given as caucauasu, meaning counsel or adviser, absorbed from local Native languages into colonial speech. Other theories point to a club of Boston shipyard caulkers. No one can prove which is right.

However it began, the caucus became a building block of American politics, the smoky back room where the real decisions were once made, and later a public, sometimes chaotic, form of grassroots democracy in states like Iowa.

Origin

American term from 1760s Boston; likely from an Algonquian word for counsel, though the origin is disputed.

Why it matters

The caucus is one of the oldest pieces of American political machinery, and one of the most mysterious in name. Whether it came from a Native word for counsel or a guild of dockworkers, it points to the same thing: politics begins not at the ballot box but in the room where people gather, argue, and decide who to back.
