Senator Blue Slip
Remember when Dick Durbin did the unthinkable and broke with Senate tradition to allow the Majority Whip to also chair a committee, all so that Maoist Sheldon Whitehouse wouldn’t chair it? Durbin loves to talk about Senate traditions, even though he broke them himself. As such, he is really the Senator from Blue Slip Fantasy Land rather than the Senator from Illinois.
Gotta keep those Senate traditions up. So long as they help Republicans anyway.
