In 1994, when the Republicans regained control of the Senate and the Judiciary Committee, Orrin Hatch became its chairman. He championed the use of the "blue slip," a process whereby if either Senator from a judicial nominee's state objected, that nominee's appointment prospects were dead. Yes, that's right, one Senator could torpedo a nominee.
In 2001, when the nominees coming up were named by a Republican president, Hatch, possibly flashing back to his roots of Mormon disingenuousness, suddenly had a revelation: Nominees could only be "blue slipped" if BOTH Senators from their home state objected. Suddenly, blue slips practically disappeared from the Senate.
But they didn't disappear entirely, so in 2003, Hatch went even further to state that even if both of a state's Senstors blue slipped a nominee (gee, are there any large states with two Democratic Senators, like maybe California?) it wouldn't stop a nomination.
Then, a few weeks later, Hatch repealed Rule IV. Previously, if a nominee couldn't get at least one minority vote, it stayed in committee. Now, the great and powerful Hatch decreed, if a nominee merely garnered a majority of the Judiciary Committee's votes, that was sufficient to move the nomination out of committee and to the floor. The Judiciary Committee is composed, as are all Senate committees and subcommittees of a majorty of Republican members, according to their status as the majority party in the Senate.
