The Gang of Fourteen led by McCain and Graham put the kibosh on that! If the Republicans had stood up to the Dems and changed the senate rules to break the impasse, I think things would be different today.
And today, if the Dims could prevent filibusters on judges, now? I hated McPain for doing it, but maybe, just maybe some coalition of Sensebrenner types could block a Bush liberal-judicial appointment the Dims demanded of him, and keep us in judicial-appointment gridlock for two years; giving the conservative base strong motivation in 2008.
