I follow this stuff pretty closely, and haven’t seen much of anything about the blue slip before today. A quick search shows two hits yesterday from Mother Jones and Media Matters. I found a few other mentions of the blue slip on other news sites, but not much.
I’m not sure if these articles are serving as a pre-emptive CYA for the inability of the President to appoint liberal dreamboats to the federal judiciary, or a preemptive attack on the GOP for using their last arrow in the quiver to stop nominations.
In any event, I always find it convenient for many outlets on the same side of the aisle to circle and focus on a single topic in a very short span. Maybe one day I’ll get the memos that go out.
