Monday night, JD’s was packed, more so than usual because it was the day before the primaries, and the race was getting tight. “These are our predictions,” said Scott Beale, a longtime volunteer with Rock the Vote, who had dispatched a delegation to New Hampshire four days ago. Beale handed me a beer coaster with some very precise numbers on it: Kerry — 30.3; Dean — 27.7; Edwards — 16.7; Clark — 13.4; Lieberman — 8.3; Kucinich — 1.4. The volunteers foresaw a surprise Dean run and were hoping for Edwards to do better than he had been polling the day before, especially since they were still stoked from an Edwards shoutout for Rock the Vote at the Palace earlier that night. “Why the decimal points?” I asked Holly Teresi, who was sitting next to me. Teresi is the communications director for the Youth Vote Coalition, of which Rock the Vote is a member. She handed me another beer coaster with a set of predictions from all five people at the coalition’s booth, with a column at the side that was averaged by row to get an aggregate prediction. Impressive. “We’re Ivy League,” said Teresi.
