Weekly Standard:

No longer will “blue slips” be allowed to deny a nominee a Senate Judiciary Committee hearing and vote on confirmation. In the past, senators have sometimes barred a nominee from their state by refusing to return their slip to the committee, thus preventing a hearing and confirmation.

“The majority”—that is, Republicans—will treat a blue slip “as simply notification of how you’re going to vote, not as an opportunity to blackball,” McConnell told me. The use of blue slips, he noted, is not a Senate rule and has “been honored in the breach over the years.” Now it won’t be honored at all.
