So after reading the link you post you thing that speeding things thru the Senate, limiting debate and eventually the Congress is a good thing? This is antithetical to what the founders believed and intended.
Not the best, but based on comments made by people on this forum, it seemed McConnell gave up everything and totally capitulated.. He didn’t.. Credibility goes to hell when people overact..
Historically, the minority didn't use the power to prevent a bill from being brought up for debate. I think that practice started becoming common around 2008 or so.
Anyway, a determined group of 41 senators can still block passage of anything. And, FWIW, the power to block bringing something to the floor was useless. The senate would often debate the bill, even though it wasn't up for consideration.
As for what the founders intended, I am quite sure they did not intend for a minority of the senate to control.
