Remember when Stacey Abrams career was over with when she lost the Georgia Governor's election to a Republican who cheated?????? She ended up costing the Republican Party the State of Georgia in the General Election for President, and the ultimately the Senate.
Then there's Merrick Garland, who McConnell refused to even interview for the Supreme Court. His career was over too when he wasn't seated, or even considered by the Republican Senate. How's that turning out for Republicans?
You also wrote off and laughed at Joe Biden and yet "Poopy Pants Joe" has achieved more legislatively, in his first 18 months as President, than any US President in history. On the world stage, he got OPEC to open up the taps, re-united, strengthened and enlarged NATO, and provided real fire power to the Ukrainians to held them drive back the Russians.
Donald Trump isn't being taken down by Democrats. He's being taken down by the Republicans who worked with him and for him. They're the ones testifying in front of the January 6th Committee. They're the ones accusing the President of conspiring to overthrow the government. One of his most trusted employees informed the FBI about the boxes in the basement of Mar-a-lago, and that Trump's lawyers lied when they said all Classified and above documents had been returned.
Christopher Wray, the guy who Trump appointed, lead the serving of a search warrant obtained on information provided by a current Trump employee, that Trump was in violation of the Espionage Act, and had deceived the DOJ as to what documents were in his possession, and refused to return them in accordance with the law, and a Grand Jury Subpoena.
Trump is now having problems finding lawyers. Since so many of those lawyers, who assisted Trump in his business dealings have ended up under federal or state investigation, disbarred, arrested, convicted, and/or jailed, it would seem to be a bad career move to hire on, especially given that before he became a "target" of an investigation in Georgia, Rudy Guilliani was complaining Trump hadn't paid him.
Cheney's career is just beginning. "If you strike me down, I shall become more powerful than you can possibly imagine". Cheney is transferring all of her campaign donations into a PAC with the stated goal of keeping Donald Trump from ever holding public office again.
