The filibuster shouldn’t exist. Period. It’s long expired milk being used as a tool for marketing obstruction to prevent the governmening from government at all, bringing the Senate to a useless pudding off toothless geriatrics cashing checks. For a decades the public facing strategy of the GOP has been to not pass laws and only legislate from the bench, and if they were ever forced to actually publicly vote on their unpopular policy on a regular basis even their lying media empire couldn’t keep up. It would be a disaster for them and literally the single worst case scenario for the entire Republican party.
That’s why the people most opposed to the removal are the GOP and the worst of the worst corrupt Democrats, and why the excuse if based around “norms” and the threat of vague future uses and not about what positive action could be taken now. The GOP does not want to reverse popular legal action in a tit for tat.
