Howard Fineman was on the Imus program about an hour ago and said that everyone throwing their hat into the ring are "Inside the Beltway" types. To him that means there is very little grass-roots support for a democrat candidate at this time.
He also feels this is why Hillary! is in the weeds and watching.
Hillary wants any and all of them to be sacrificial lambs for 2004. She is waiting for re-election in 2006, followed by a presidential run in 2008 when there is no incumbent.
