The man made the mistake of thinking things were politics as usual, the problem was that the democrats have been acting increasingly unhinged since 2016 and have been doing things like using weaponized legalism, terrorism, and have in a few cases strait up murdered their political opasition. They have currently arrested the most likely person to run as president on pretty damned flimsy premisese.
Then the GOPs current establishment decided to visibly and openly stab their base in the back in 22 creating a mutalated victory in what should have been a clean sweep. The mood for compromise after dealing with all of this fuckery is decidedly over. The time for politics as usual are over.
Macarthy should have understood this while he was making those promises, as a politition he should have been able to read the fucking room. But he did not and he's now the first speaker to be successfully ousted like this in over a century. A lesson to the others.
