New Hampshire senator Judd Gregg acted as Democratic doppelgangers in 2000 and 2004. For Gregg, playing Gore was a piece of cake. He claimed that the then-vice president was mechanical, scientific, and uber-predictable. But he had a tougher time playing Kerry. He maintained that the notoriously flip-flopping senator was hard to pin down because he went in a few different directions when he spoke.
