I seem to remember the rats filibustering and threatening to filibuster judicial nominees when the constitution requires a majority(51) not 60 to break a filibuster.
Remember the so called "nuclear option" to change the rules to get approvals with majority vote.
that was a scheme to get their way.
Why wouldn't they do that again expecially now that they have majorities.
That is true about judicial nominees, but not bills.
More on what you just alluded to:
