Just gonna point out that the proto-maga IE the Tea Party dipshits have their roots in things like the 90s rightwing militia movement and they arguably didn't gain full control of the Republican party until 2016 IMO even if they were a massive faction. Hell historically the faction that would evolve into the New Deal Democrats had its roots in various 1800s labor movements and didn't get to notability until the 1930s same general deal for the Square Deal Republicans just a bit earlier.

Reform of this scale takes ages since you basically need to reach a saturation point, which basically requires constant pressure a bit like an inline fuel filter if the pressure stops the filter drys up. But I have noticed change since 2016 more specifically with younger libs who I wouldn't call economic progressives by any means being supportive of things like universal healthcare, expansion of welfare, demilitarization, and shrinking the police state. The problem is we have probably only reached 25 percent saturation at best, which means unless people get real comfortable with a lot of murder of the old guard it's gonna take awhile still to see active improvement.
