Bill Quick presents the STFU argument:

The brutal truth is that the Second was saved today thanks to the actions of conservatives who rebelled against George Bush and forced him to put Roberts and Alito on the court. Had his preferred nominees, Alberto Gonzales and Harriet Miers, been nominated and ratified, the decision we would have seen today would have been 5-4 in the opposite direction, with Gonzales joining with the other four liberals to respect the Bush administration’s request that the DC law not be overturned.

That’s about as on-point as it’ll ever get.
