Unlimited debate subject to supermajority cloture made sense when the Senators were ambassadors to Washington appointed by State governments.
It would destabilize the Union to allow 25 States to legislate in a manner repugnant to 23 States.
And, tell the truth - if a Senator is simply a super-congressman, and the Senate functions under the same rules as the House, why not abolish it?
We actually NEED a Council of States to wield control over things that the permanent government at Washington comes up with. But today’s Senate isn’t it.
I agree with you.
