Makes NO difference. Bush had totally control over who will be nominated and all it takes is 50 votes for confirmation along with Cheney's vote. There are NO excuses this time for another Souter, O'Connor or Kennedy. Either Bush and the Republicans do what they promised or they can watch their presidency and party fall like a house of cards.
I will never vote for Republican again if Bush screws this up. It's the ONLY reason I voted for him.
I'll waste my vote on a 3rd party candidate if we can't get a conservative judge on the bench with a majority in congress.
