I’m listening—...
Trump told people "you're OK".
It is what people need to hear
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.
