"...Less than two weeks ago, Senate GOP leaders made it clear they were getting interested in making the change.
"There is no reason to burn a lot of time on the floor for noncontroversial nominees just because you can," Sen. John Cornyn, R-Texas, said. "And it's slowing down the process. There are a lot of important vacancies that exist."
Senate Majority Leader Mitch McConnell, R-Ky., said Democrats have forced an "extraordinary level of obstruction" on even noncontroversial nominees.
But even if Blunt's committee approves the resolution, it's not clear it can pass the Senate. Republicans control just 51 votes, and they'll need 60 votes to advance it to a final vote on the floor.
That means it will need support from Democrats, and it's not clear Democrats are ready to help the GOP along with its plan to speed up the process of confirming Trump's picks.
Republicans are hopeful, however, because both parties agreed in 2013 to make the same change, and when that rule came up, it passed 78-16...."

The question is why the Republicans let it change back.

And if they don't get 60 votes, there is an alternative. Work longer, just like people in the real world do. If the Dems want to obstruct things, then have the Senate work 8am to midnight 6 days a week.
