Tea party was the clear predecessor to the maga movement, with its nucleation point being simple racist backlash against obama and trump being personally & directly involved in stoking that racism. In retrospect it obviously laid the groundwork for trump's movement, and I can't see any direct link from occupy to tea party other than perhaps some individuals like tunney.
The tea party was a right wing populist movement and maga is an extreme right populist movement that emerges a handful of years later, with astounding overlap in membership, and you don't think they're connected? ok.
Trump told people "you're OK".
It is what people need to hear
