I mean it's their loss no matter who they try to blame. The transition team already isn't expecting midterms to go well for Trump, so they're trying to set as much up they can on day one. One of the things Trump wants to bring back is schedule F so that he can start firing people.
There's a problem with tat though. It's statutory language indicates that departments will require a determination for reclassification. Absent that, everyone fired would have an opportunity to file suit and if it's enough of any given State opens the State to file Federal suit to block the executive order.
One of the things they can do to speed things up would be to have those rosters right now to review. But that they're getting blocked because of failure to work with legally required ethics, means they'll be behind the ball on day one. As much as Trump wants to, all those employees have legally binding contracts that require careful consideration to undo them without massive challenge.
With the President-elect's team not looking positive for midterms, they've got a lot of things to get done on their to-do list and not exactly a lot of time to do them in. Trump's agenda is already starting to suffer too much water for too narrow a drain. Every minute he's delayed is putting those to-do items from "getting done" to "must prioritize this list".
But all of this is Trump's scales to balance. He can skip out of the ethics filings but that comes with the cost of having a bit over 70 day delay to get some of the more basic things done. And right now, he's got time on hand. Confirmation hearings aren't going on, which even Republicans in the Senate are going to be asking for favors for their State in order to stomach some of the people Trump is passing over. This is one of the reasons Trump wants to skip all of this and have recessed appointments. Trump isn't interested in playing the favors game, but every single person in Congress has their career to think about long after Trump is gone. They want wins they can go home with.
So waiting to day one means he'll need teams reviewing the employment roster for his schedule F idea and he'll need teams in Congress helping to convince members to get his agenda enacted. He's going to have a lot of stretched thin groups which means getting things done are going to take longer to get done. Time that Trump doesn't have.
So he can blame Biden all he wants, his followers can believe whatever they want to believe. At the end of the day, Trump's agenda either gets implemented or it doesn't. It's a pretty binary outcome. Trump is going to whine about Biden or Democrats when his policy ideas fall apart, that's just how Trump operates. He has no ability to see the issues within himself and learn from them to get better. So there's no stopping Trump from blaming everyone but himself, that's just never going to happen.
So Trump will absolutely say that, the more important thing is his policy not getting any feet.
Republicans are going to cry the whole way for the next four years. That's just who they are. We have to look past that dumb shit and see if things are getting green-lit or waiting on incompetence to clear out. Did Trump get it enacted or not? That's the only thing that matters, all the other shit is just the usual bullshit Republicans cry about. We've long left the whole "meet in the middle" thing, the only thing that should matter is if Trump gets any of his policy enacted or not. The EO stuff, everything he throws is just giving more ideas on which avenues to close off when Democrats take the trifecta next.
