JIM LO SCALZO FOR USN&WR

Iowa's method of picking winners is esoteric and unique. The act of caucusing is part dodge-ball (don't get eliminated), part tug-of-war (bring opponents to your side, by coercion if necessary), and part high-school popularity contest (have the most followers). In 2004, photographer Jim Lo Scalzo spent Caucus Night in a turn-of-the-century one-room schoolhouse in Cumming, Iowa. By night's end, the results from Cumming and other Warren County precincts had been combined with tallies from the state's 98 remaining counties. The result was duly recorded: Kerry "won" Iowa with 38 percent of the delegates, Edwards took second, and Dean finished a weak third.
