It was an illegal act of gall, upending his earlier removal by the 25th Amendment. But the Temp-Prez was hated by everyone, and after the failed (V)ICE invasion of Portland, something had to be done. Real-Prez’s chutzpah had worked, and even the displaced Temp-Prez (who returned rather unconstitutionally to Veep) was praising him by the end of the day. But the dramatic move was all theater – Real-Prez was the power brokers’ only hope, and they preferred Real-Prez’s unpredictable insanity to the charismatically challenged Temp-Prez.
And since they had as yet not found a new Veep, dumping Temp-Prez would have elevated the Speaker, who was a Dee, and that would be infinitely worse. The coup had all been planned and approved by the power brokers and was accompanied by a great deal of back room maneuvering, the details of which are still mostly secret.
