Trump has had the same MO for decades and it has always served him well. Look at this way. The swamp/globalists threw everything they had against him. Everything. Treachery. Mass disinformation campaigns. Mass phycological manipulation of the public. Multiple impeachments. Yet the ONLY way they defeated him was a mass gaming of the system and an outright internal coup. He knows that now. He's adjusted.
He doesn't play inside the boundaries that the globalists set for those who want political power. He destroys the boundaries.
You just expressed the problem with Trump: “It’s served me well, why change?” But did his people really serve him well at all?
