It works like this. Senate Majority Leader Bill Frist attempts to gradually lower from 60 to 51 the votes needed to end a filibuster. That fails, because it requires 60 votes to change a Senate rule and the Republicans have only 50. Then Vice President Cheney rules on a constitutional point of order that 51 votes can end a filibuster of nominations. The Senate parliamentarian, appointed by Republicans, upholds his ruling. The filibuster blocking Priscilla Owen is ended. (And the road is cleared for the right-wing Supreme Court justices Bush will appoint later in his first term.) It would be quite an end to a Senate procedure in effect since George Washington held office.
None other than George Will would oppose such a thing. Or, at least, he did when the Republicans were in the minority but now they´re in a majority so he wouldn´t anymore.
