There’s no real reason to filibuster Gorsuch. He won’t change the makeup of the court as he’ll be replacing Scalia. By deciding to avenge Garland, the Dems are throwing away the filibuster, which means that when one of the liberal justices shuffles off, and they’re faced with an awful appointment that might attract a Republican or two against cloture, the Republican President will only need 51 votes to confirm.
While I think minority rule in the Senate is an overall bad idea, the Dems are opening up a world in which Supreme court justices are all appointed and confirmed by party line votes.
Do they really want to go there?
