Warning, very hot take incoming:
In a way, Barr's vagueness may have given this whole shebang a second wind. Congressional democrats are almost certain to get Barr, Rosenstein and even Mueller to testify. I'm not sure if thats a good thing or bad things for dems politically, but its pretty clear this isnt over.
Probably a bad thing. Most people don't care about this and it's time to move on.
Completely agree with this. Democrats should just take the l on this one and move on. If they let it fade, it's likely nobody will care in a month, let alone by November 2020. Dragging it out when it probably isn't going to yield much with exponentially increasing risk is a bad idea.
