I expect some of it is astroturf like the that white republican guy who had a fake black guy alt and spent his time calling democrats racist. I think people underestimate the sheer amount of billionaire money the republican aparatus has and why its still going despite it being widely unpopular.
The other thing is Biden actually has made some good appointments but the corporate media doesn’t like them so they don’t, for instance, want to praise the NLRB appointments.
