McConnell attacked Democrats for changing the Senate rules but he no made to promise to reverse it. From McConnell:
And when the Majority Leader decided a few weeks back to defy bipartisan opposition by changing the rules that govern this place with a simple majority vote, he broke something. But our response can’t be to just sit back and accept the demise of the Senate. This body has survived mistakes and excesses before. And even after some of its worst periods, it’s found a way to spring back, and to be the place where even the starkest differences and the fiercest ideological disputes are hashed out by consensus and mutual respect. Indeed, it’s during periods of the greatest polarization that the value of the Senate is most clearly seen.
If Senate Republicans truly thought allowing a Senate minority to obstruct a president’s ability to fill his own cabinet was critical for a well-run country, they would be promising to restore the old system as soon as possible. Instead Republicans like to complain about the change but they have already accepted it will be the new norm going forward.
The Senate has been permanently changed.
