"if Edwards drops out, that may encourage Gore to drop in. His presence will tear the Democrats to pieces."
IMO, Gores in either way. He's just waiting for Hillary and Obama to draw blood and weaken each other.
Edwards doesn't have a chance. Gore probably has a better chance than Obama and will neuter Hillary's support.
I anticipate we will see cannibalistic behavior among the demoratic hopefuls in the near future.
