The Blue Slip Policy
The next fight over judicial nominations will involve the custom that the Senate does not take up a district or circuit nominee if one home state senator objects. Declining to return the so-called “blue slip” is a way of blocking a nominee and asserting a senator’s right to be consulted by the White House. Senator Al Franken, for instance, is refusing to return his blue slip on David Stras, a nominee from Minnesota for the Eighth Circuit.
Maybe this is simplistic, but it strikes me that the blue slip policy makes more sense only if both home state senators object to somebody. If only one does, that gives an individual senator too much power to block a nomination (basically, a total veto). If both senators from the relevant state object, though, then I think there is a federalism interest that other senators should respect, though of course it’s their call.
