Nahhh. He is in the same spot as LBJ in 1968. Spending out of control and the government doesn't need another big dose of debt on its books.
No nationalization.
If anything, he will try to do the same as Trump and keep them in limbo.
I think the next step in the legal process will be the challenging of the running of the conservatorship itself. And at some point the government will ultimately lose on this. When? Who knows?
