Zell Miller would certainly join this movement. As would Sam Nunn, probably. Plus, John Breaux led the commission that suggested private accounts as a reform measure.
Aside from Stenholm, the President could also probably even enlist Martin Frost -- a smart man, though a liberal, who also has some scores to settle with the likes of Nancy Pelosi and Howard Dean.
Kerrey (then from Nebraska - had been governer and was senator[?]) seemed to be a fairly reasonable person in the primaries, but was lost in the dust when the Clintons admitted to adultery on national tv. He has since shown number of strange liberal ideas (including pro-Sadaam bias), but I am convinced, he would have not been the national disaster that we had in the previous administration.
