Biden will be looked at like Reagan. It has been three decades yet people fail to realise that most of the messes of both Republican and Democrat presents were seeded by Reagan.
It is possible that there are more Reagan Democrats today than Reagan Republican. On this site, a good amount of the republicans seen unaware of his political profile. Maybe they were not around. (I was not.) I would say that Republican presidents hold less sway then powerful Republican senators. Like McCain over Bush. And McConnell over Trump.
