The Dems will be stumbling over themselves to make these changes as soon as they regain power in the Senate. No reason to postpone the inevitable.
The Senate is already well positioned to check the excesses of the House by virtue of its composition (2 per state) - it does not need a 60-vote supermajority requirement for every Tom, Dick and Harry that is appointed to head a team of bureaucrats.
Absolutely, the Rats even said they were willing to do this but not at this time.
Thank the Lord Mitch didn’t stand down.
