I suspect in the aftermath of this administration, the power of the President as a whole is going to be massively stripped back.
That seems highly questionable given how little pushback Trump got in congress, and it was almost entirely along party lines. What makes you think they'll suddenly grow a spine in 3 years?
I think it'll be interesting to see what the consequences are. In India, it used to be (I haven't lived there in decades) pretty par for the course for a new party to come into power and jail all the previous party's heads for corruption and then when it yoyos over the inverse would happen. That would be a worse outcome for the US, I think. It would stall any significant action from the government.
That might work out well for the Republicans - "rule by executive order" started under the Obama administration.
I thought that would happen after the first Trump term. It did not.
The second one has made an even stronger case for doing so though.
Has not happened after other catastrophic administrations. Each party likes the power when they get hold of it.
