No one says 100 are needed - 60 would do just fine.
51 is all it takes under the Constitution. Or has that been subverted while the people were distracted by bread and circuses?
Be serious. If we had 66 GOP senators, we'd still be hearing that the 7 RINO Senators can't assure us of a filibuster-proof majority, and thus only moderate-to-liberal policy will do. The Bush apologists on this site will never admit that Bush actually made an error, and will continue to move the goalposts to make excuses for these awful decisions.
