These are the most interesting poll numbers that have come out lately, IMO.
Rasmussen (not certain about their reputation) put out head-to-head Dem matchups - including post-Gore Dean bounce.
Dean-Gep and Clark-Gep ultracompetitive
Post-Gore bounce
I would guess that the "Gore bounce" would be very soft support, but that's only a supposition. I would say that Dean is stronger than I thought he'd be in head-to-heads, but he has not demonstrated the sort of strength that should lead his closest competitors to abandon their campaigns. It's my hope the Q4 numbers make some candidates realize it's just not in the cards.
