i dont think so. you also gotta question why the democratic base would support corrupt politicians anyways...its just propaganda.The problem was they were all unacceptable to the deomcrat base. Maybe their base will realize that they are the problem for voting for one of the most prolific criminals in US political history.
what happened in 2020 was biden rallied support from his fellow cronies, whereas trump didnt have a united republican party against him in 2016. in part anyways there was more.
