There is nothing that the Establishment, Left and Right, fears more than a Constitutional Crisis. I don’t know why that is but I long ago noticed this fear in none other than Bill Buckley himself. When Buckley pronounced leaning back in his telebision chair “That would be a Constitutional Crisis!” that marked the end of the discussion.
It’s because the USA is still a very young Federation, and the last Constitutional Crisis led to the Civil War.
That’s why the Repub’s give the Dems a pass a lot of times. They are scared of another Civil War. The Dems on the other hand use that as their Ace card.
