Justice David Souter's retirement gives President Obama the opportunity to replace him with a true progressive - the mirror opposite of Scalia, Thomas, Roberts, and Alito.
Sure rightwingers will scream, Republicans will threaten a filibuster, Democratic Corporatists like Ben Nelson will threaten to join them, and The Washington Pundits will insist they are Absolutely Right. But who cares? We elected President Obama, not them. And the majority of Americans support our populist agenda, not their corporatist one.
Ruth Bader Ginsburg is the only progressive now on the Court. As progressives, we must not settle for more Corporatists like Stephen Breyer.
