Who should be the next LP presidential candidate?

Given the LP's track record for picking presidential candidates, including, for example, a dead-beat dad, a shameless self-promoter and most recently a virtual unknown (who may have been articulate, but an unknown nonetheless), it seems appropriate to start asking the question: Who can best represent the principles and values of the LP in its most visible public position during the next presidential election?

Some have suggested John Mackey, the brains behind Whole Foods Market, a national grocery chain for the granola crowd. Setting aside the substantial question whether he has any interest, I think it will be hard to find another candidate with advance coverage such as this.
