The colder something is, the less molecular movement there is. Way back in high school science you probably heard about 0 Kelvin (“absolute zero”). That’s only a theoretical temperature because at that point there would be absolutely no molecular movement at all. (For a fascinating discussion of temperature see here — and don’t cry when you read it was designed for middle school teaching.)

To put it in NH terms, Lieberman registers 0 Kelvin in today’s ARG tracking poll – no movement. The Dean and Clark campaigns represent high temperatures – moving all around randomly with no idea where they’re going. And Kerry and Edwards are cooler molecules moving more slowly and deliberately
