Did you know?

It’s hard to pinpoint the exact origins of caucus, but some scholars think the word may have developed from an Algonquian term for a group of elders, leaders, or advisers. An early example of the word in use comes from John Adams, who in February of 1763 reported that the Boston “caucus club,” a group of politically active city elders, would soon meet and that, at the meetings, those present would “smoke tobacco till you [could not] see from one end of the garret to the other.” A similarly opaque smoke screen seems to cloud the history of caucus to this day.
