Meh. Whatever.
His fragile little-man ego won't cope, but he'll be gone.
Gone from any real power, yes. But I'm sure he'll work as hard as he possibly can to make sure attention is focused on him as much as possible during the Biden presidency. While Fox News may have dropped him, there will be plenty of talk radio willing to host the former President and give him a platform to continue claiming loudly that some shadowy Democrat conspiracy deprived him of a second term, and that all those loyal patriots out there should keep fighting for the Republic.
What does scare me, however, is that former Presidents continue to receive top secret briefings until they die. The idea is that the former President's experience during his administration will prove useful to some future President continuing to deal with the same issues. But his knowledge has to be current in order for that plan to work. We'll have an ex-President deeply in debt, continuing to be fed official state secrets, violating laws left and right with impunity, and desperate for continued relevance. If Mother Nature doesn't continue ravaging his health, let's hope the State of New York is able to make good on the threat of criminal prosecution. He needs to be more out of circulation than simply not being President anymore.
[Sidney Powell's] been fired.....
Hey, Donald J. Trump hires only "the best people." In order to litigate in various state and federal courts, you need to hire attorneys who are admitted to the bar there, and who understand the state's procedural rules and the ground rules of each individual court. But of course the Trump team sends in people like Powell and Giuliani to dictate the desired strategy to these local counselors. And as those Trump operatives become increasing unhinged, no serious attorney wants to be associated with them. So ultimately it comes down to a practical question. If literally no one wants to work as local counsel for Trump For President anymore, then he literally can't accomplish the work to prosecute his case. So he has no choice but to cut Powell loose, no matter how much he wants to play the QAnon card for theatrical effect.
Even in large cities, legal communities are relatively small. Everyone knows everyone else, at least at the firm level. Every attorney knows all the judges and all the judges know all the attorneys. Getting embroiled in something like nutjob conspiracy theories in the serious practice of law will taint their reputations, even if they previously didn't have much of one. Nobody forgets that time you got laughed out of court after pitching a conspiracy theory with no evidence. I'm sure there would be plenty of firms willing to litigate Trump's election challenges as long as they were able to develop the strategy. But only the most desperate firms with nothing to lose, I think, would be willing to let themselves be led around by the likes of Powell and Giuliani.
