Thats a non-issue. With a majority already, they can vote to remove the fillibuster rule if they so choose...........
The gang of 14 prevented the Reps from doing just this.... the dems have no such ethical concerns. It will likely be a long time before the R’s are back in the senatorial majority so the D’s may just do that - remove the present filibuster rule... Of couse even with 42 or 43 R senators, they don’t have 40 with guts to stop the socialism from moving forward!
And don’t forget such stalwart republicans as Christine (The Pristine)Todd Whitman and Arlen Spector.
