After initially accepting the ass whooping he got in the midterms, Trump is now - feebly - shifting to a little election denial. It doesn't seem to have much juice behind it, so much as various online MAGATs grasping at any piece of flotsam that drifts by.
JD Vance tried to float the Iran Balloon being the cause of the wipeout. This at least fits with his previously expressed skepticism in military adventurism. His reward was to be sidelined into the bullshit corruption scam of complaining about Blue States and Cities. The thing is, you can't jettison the Vice President.
Because the GOP exists currently as a cult of personality to coddle the man-baby in the Oval Office, there can be no blame that falls on his narrow, withered shoulders. If the magnitude of what happens really sinks in with Trump, he will need to find someone to scapegoat. The original scapegoat was a literal goat that was symbolically freighted with the sins of the village and then driven into the wilderness.
Two obvious fall guy appear. It is necessary to note that Trump has zero problems firing women, but has yet to really being the axe down in a dude. Still, two guys.
The first is Pete Hegseth, obviously. He was the cheerleader of the Iran war and the architect of our defeat there. If you buy into Vance's criticism, he's a natural scapegoat. Make him the symbol of a failed war, get in someone who isn't a shit posting influencer and made restore some sanity to America's defense establishment.
The second is Howard Lutnick. There also seems to be a sense that it was all the corruption that cost Republicans, and Lutnick is about as corrupt as you can get - unless you're a member of the Trump family. The Jensen Huang story has all the markings of a story that has legs. You've got spies, sex and cover-ups in the government. Juicy. Lutnick seems to be at the heart of covering for Huang, though clearly Trump was right there with him.
There remains the problem of what a Democratic Congress can do, considering how compromised the Department of Justice is. They can subpoena, but I doubt they can resurrect the independent prosecutors. Ultimately, you can expose people's wrong doing, but Trump still has the pardon power.
I think the real angle will be the inevitable turning on each other that we can expect from these wretched things in Trump's decaying orbit. There will be scapegoating and back stabbing because these are terrible people and terrible people do terrible things. For the past two years, they have been doing it to each other, but now we can expect them to do it to each other.
