The DUmmies probably think of the remaining Justices much as the "Fantastic Four", who they hope will defend the world against the advance of right-wing hegemony and make the country safe for Progressivism.
In fact, let's make a comparison between this group and the comic characters (the F4, that is)-
Mister Fantastic: The soon-to-retire J.P. Stevens, "Liberal Lion" of the Court.
Human Torch: Stephen Breyer, never averse to setting fire to the Constitution when necessary.
Invisible Woman: Sonia Sotomayor- not much to see there, but the 'wise Latino' will undoubtedly come through.
The Thing: Well....
