Reagan happened because conservatives realized people don't like conservatives.
So they invented Faux News (memo in Nixon's presidential library) so that voters would never hold Republicans accountable again, and then started running charismatic figureheads to eventually take the fall years after leaving office.
Blaming Reagan (who is undoubtedly a piece of shit) is letting the real problem off the hook.
I don't remember Reagan, but I remember GW, and it was the same thing. When we're finally rid of trump, the next will be even worse, and still taking orders from the same conservative machine that was feeding Reagan his talking points.
So hate Reagan all you want, but don't forget to hate the other people who were actually the ones in control. Because that machine is still running, it's the one behind project 2025, not trump's dumbass.
