Sincerely curious as to your thoughts here, as I would guess the other way.
The Senate currently requires 60 votes to move non-budgetary legislation. To remove this rule they would need Manchin's vote to get to 50+VP which he has said he will not give. Even if Manchin agreed to drop fillibuster rule he would then have to vote for gun control, and other than an extension of existing background checks to gun shows and other third party private sales he has said he doesn't support going further. And even if Manchin changes his mind, there are at least 3 or 4 other Dem Senators that will tread lightly on the issue. On the flip side the House rules by 50.001% and already has a 10 vote cushion. While the house does have some members in "swing" districts that may also tread lightly, all in all the senate seems a lot safer.
The real risk is not in 2021, but if the Trumpists continue to drive suburban and other moderate conservatives away from the party there is a real risk in 2022 or 2024 that the Dems get to 60 in the senate. And then you can say goodbye to a lot more than the 2A - it will be all AOC/Warren/Bernie all the time. Time for the rightest of the right to see the writing on the wall and start dancing with the broad coalition of moderate conservatives.
There is more than one Democrat in the house that is closer to center, there is only one of those in the senate. There also appears to be a lower percentage of pseudo-conservative Republicans in the house. House members are much closer to their constituents due to their shorter terms and smaller areas of representation. You can have vast areas of a state go essentially unrepresented by their senators due to their elections being statewide.
I don’t trust Manchin to stick to his guns. It’s been a long time since he voted counter to rest of his party on anything meaningful.
I don’t trust Swamp Rat McConnel or his father-in-law.
I don’t trust Rubio.
Murkowski and Collins are total libs that just keep the R in front of their names and do occasional conservative things because they have to to win in their states.
This seems right up Rand Paul’s alley, but he does really weird things sometimes. He’s either mentally defective or perhaps being blackmailed. We would have repealed Obama Care if he had voted on the first more conservative repeal, but he voted against it and claimed that it wasn’t conservative enough. Republicans rewrote the repeal bill to be more liberal so that they could pick up Collins or Murkowski, and Rand Paul then voted for the more liberal version, but McCain came in and did voted against it even though he had just won re-election claiming that he would repeal it. Something is not right with Rand Paul.
Mitt Romney is a liberal.
John Cornyn is a liberal.
The Democrats have the majority in the senate 53-47 with Collins, Murkowski and Romney. Manchin is the only one that might vote to get rid of the filibuster.
According to my understanding, the senate filibuster rule is not constitutional law. Schumer can theoretically hold a vote whether he has 60 vote consent any time he wants, then Biden can sign a bill with only 51 senate votes, or 50 senate votes plus Harris, and will become law, and that will likely hold up in the Supreme Court. Would he prefer that he stayed within senate rules by changing the rules with a 51-49 vote? Sure. When he does either one, it will be after a major controversial bill fails with 3-7 Republican supporters.
