Question: Assuming one of the current Democratic Presidential candidates wins in Nov 08, who would you most want to see as VEEP?

I thought this was an important question: Assuming one of the current Democratic (or Heaven forbid Republican) Presidential candidates wins in Nov 08, who would you most want to see as VEEP?
We've had some pretty crappy vice presidents in the last few decades (except for Al Gore, although many would agree in 2000 he chose a crappy running mate) and we really want to have a solid progressive Dem in the Number Two seat, just in case...
And of course the VP serves as President of the US Senate, that's kind of important too.
So if your first choice for POTUS actually gets elected, who would you want waiting in the wings?
Cheers,

One thing's for sure: before the next VP moves in, it's gonna need a visit from the Orkin man, a Holy man and maybe the Ghostbusters, 'cuz right now it's occupied by EVIL SPIRITS!
