I tend to disagree...I think the reason they haven't jumped yet is becuz they were really never courted that aggressively by Dubyuh and the GOP. Think about it, when Jeffords took his Lib'ral Vote to the RATS, all of a sudden we had Little Tommy Dasshole as the personalization of the DemonRAT Obstructionists, when before the RINO- Wing (Jawn Wahnah, McStain, Chaffee, Snowe, Collins, Jeffords, etc.) could undercut Conservative Legislation under the radar screen, while the Medyuh shrilly cackled at the GOP's inability to move legislation despite controlling the Oval Office and both Branches of the Legislature.
Now, it's become Dubyuh versus Dasshole in November, despite neither of them being on the ticket!!
