“A caucus is a closed meeting of equals, the word probably derived from the Algonquin cau-cau-asu, translated as ‘proponent’ or ‘advisor.’ At 6:30 pm on January 19th, Iowaís 1,993 precinct caucuses were called to order, beginning the first step of an elaborate six-month process… Although the count of state delegate equivalents is at least two steps removed from the actual votes cast by caucus attendees, the count is about as close as we can get to actual voting data, and deserves some study. Iowa is an interesting state because its 99 counties are all roughly the same size and shape.”
