First, when you need 60 votes, you do not control the Senate.
The reason it’s unhelpful in this case is that it legitimizes Democrats’ talking point that Republicans could end this shutdown any time they want to. And that could make it harder for Republicans to shake the blame they’ve been saddled with.
It’s been pretty remarkable how much Americans have continued to blame Republicans more than Democrats for the shutdown, despite it being Democrats who are seeking the concession (i.e. an extension of the enhanced Obamacare subsidies). A Washington Post-ABC News poll released Thursday showed 45% of Americans mainly blamed Trump and the GOP, versus 33% who held Democrats responsible.
Yes, the repubs could get rid of the filibuster. But they won't. Do they realize they are losing in their shutdown efforts? They have control of the WH, the Senate, and the House. They cannot blame the Dems, when the Dems control nothing. They would rather inflict pain on millions of Americans that compromise on ACA subsidies. Everyone know trump and his cronies want to kill the ACA. The GOP House is becoming a stain on American history. They are not working, they are vacationing at home And they think they can win in 2026? These weeks of the GOP House sitting on their hands are going to be great campaign ads for Dems.
Secondly, Trump the top negotiator in the world, is as usual three steps ahead of everyone else, especially the leftwingers. He has once again put the Democrats in a checkmate position. Trump wins either way. If he's bluffing the nuclear option and the Democrats cave, the Democrats get branded as losers, and Trump continues his great economic climb. If he has to do the nuke option, the Democrats look like childish obstructors, and Trump the adult in getting people the help they need. So Republicans don't have to give an inch. Trump, in making this pronouncement, has given them cover to not negotiate. They don't have to. They've won.
Sometimes I just shake my head in sheer amazement over the gifts this man has.
