As Bumpy Jonas wrote in one of his excellent essays, Joe Biden may not be what you ordered for dinner, but if your other choice is arsenic, do you choose to eat the arsenic? Do you force your children to eat the arsenic? Voting for a president has a lot more effects than whether or not you like or hate an individual. What world will that person foster? I've had it with the Trump world.
And, by the bye, can you tell us why you think Biden is the "worst" President rather than just stating it? I'd like to know what your wider perspective tells you.
