No, when the fillibuster is gone it will be gone forever.
Of course not...first day the pubs have a majority....the dems and media will be yelping like stuck pigs for it to return...you know to be fair...
If they do this, the senate will effectively become like the House. Not only will the minority power have less power, the individual senators themselves will also lose quite a pit of power. Which makes it odd that they’d actually follow through on this, rather than come up with some Gang of 14 type of compromise,
