Not really. There is that old adage "if it ain't broke". Politicians for the most part are more interested in getting elected than sticking to principle. Give Bush 8 years of unmitigated success, and you can almost be guaranteed that the same formula will be used in 2008. Basically, the RP needs to be given a reason to reform, and the only thing that motivates politicians is getting elected. Nietzsche said "if something is falling, push it!" Basically the RP is at a crossroads right now and the only way to fix it is to break it first.
Judges are forever.
Given Dubya's track record with Judges so far, I don't really believe he will manage to get another Thomas into the Supreme Court. I think at best he will manage an O'Connor and at worst it will be a Souter.
I hope not. I was actually thinking the same thing. I'm hoping that the Senate will go 60+ Republican in '06. It is highly probable IMO that this will happen. With a supermajority it will be over for the Dems.
