There have been a number of names of possible "compromise candidates" floated by people involved with process, some less plausible-sounding than others (Marty Connor!), although picking anyone at this point who isn't on the approved list of candidates would be an act of overt political war against Eliot Spitzer. (And, therefore, not really a compromise at all.)

Isac, meanwhile, has a prediction: "They're going against Spitzer."
