Actually, if you understand how consensus government and the rule of law works, there's no objective way say that Trump was not a total failure. He broke numerous laws and norms, making governing after him more difficult. He may have destroyed his party, of which he never really was a member of or cared about other than using it for power. He's probably a Democrat at heart. He continues to put his lawyers in jail and did nothing of substance to help the country. He insulted war heroes and threatened people with violence. He stoked violence among the angry, lost souls who are always looking for someone to blame. He attracted other criminals and bad actors like flies to a pile of manure. He made his supporters look like idiots by having to keep up with his ever changing lies and BS. He lobbied hard for longtime enemies. He cheater his grass root supporters out of millions of dollars with fraudulent donation and automatic payment schemes. What a guy!
How many people are either in jail of have been convicted because of him? It's hard to keep count because the number continues to grow, like his tally of crimes.
Biden, on the other hand, has stayed mostly out of the news, letting Congress grapple with policy and strike agreements. He has not sucked up to dictators or tried to cheat regular people out of their spending money. He's passed major legislation after everyone had given up on him being able to do so. He's doing his job as temporary govt bureaucrat without making an ass out of himself. AND...he hasn't been caught sniffing some little girl's hair on camera. What else do you want?
