You can't get majority Democrats in the House to support it, forget the Senate and you want Biden to waste his time on it? Over something that has never worked in a hundred years and needs sixty votes in the Senate.
Because that was a bill carved out of Build Better Act after committee negotiations, it was finalized in congressional negotiations. It didn't come out of thin air.
You dont know that you cant get majority Democrats in the House to support it. Needs 51 votes in The Senate. You dont know how many Dems are against it until the president advocates for it.Of course its going nowhere with the party if the president says he opposes it. It has has never worked in a hundred years,but The SC has never been this unpopular in 100 years.The SCs numbers are even worst than Bidens.
That would be a valid excuse if Biden didn't side with Manchin and Sinema on Senate rules,expanding the court etc.
But we aren't even talking about court expansion here, we are simply talking about changing Senate rules and you don't even have the votes for it.
