Heard pollster John Zogby on the radio this morning. From what I remember:
--He said Wesley Clark is just a "placeholder" for those who wants to see Dean lose. If it becomes obvious that Dean isn't strong enough to force his opposition to unify behind one candidate, the Clark supporters might go back to the candidate they had supported but thought couldn't win.
--He mentions blogs, and how he sees that Dean supporters are pledging not to cause trouble if Dean isn't the nominee.
----Advice to Dean: stick to emphasizing his anti-war position rather than arguing about his electability or the inevitability of his nomination. To Kerry: emphasize ability to beat Bush.
