Empty threat given the Senate is not changing hands for the foreseeable future.
It's often forgotten, there was a filibuster rule in the House before the Senate. Stupid rule, the House got rid of it. Senate adopted one. It was valuable in the runup to the Civil War and far beyond. In our, at least my, lifetime most valuable in fighting civil rights legislation. Valuable to the dems, led by folks like Byrd and Gore. Don't want no stinken civil rights legislation. Boy, was that forgotten in a hurry. Senator McConnell, let the rule begone. Forget about the Byrds, Kennedys and McCains entranced by the nonsensical history of an ancient rule. Not a law. Or Constitutional provision. And yes, I've a political motication in noting used most effectively in opresing minorities in the US. Particularly a certain racial minority who should sue the DNC for reparations.
How about Mitch do away with it now? I’d be ok with that and you’d hear the RAT’s howl in protest....
