In my opinion the true reason behind the Republican desire to extinguish the filibuster rule has as much, if not more, to do with the Vice Presidency, rather than with judges. Although we have recently heard and read about Cheney thinking about running for President in 2008, I do not believe it. It's a red herring. Rather, I believe that soon after the filibuster is done away with, Cheney will step down, and that office will be vacant. What happens then? The 25th Amendment, Section 2, to the United States Constitution kicks in. It provides:
"Whenever there is a vacancy in the office of the Vice President, the President shall nominate a Vice President who shall take office upon confirmation by a majority vote of both Houses of Congress."
Thus, with the filibuster out of the way, Republicans can walk their pick right into office. If the filibuster remaines intact, the Democrats have a say. It's that simple.
