I might point out that the job of the President (and all others in a political position) may be challenging.
Biden is a Catholic and has beliefs about what is right and wrong that derives from that. Biden is also a patriotic American.
As a senator (and anyone as president) has sworn to uphold the constitution.
To impose his personal religious beliefs on others would violate the constitution. This is what makes the job challenging for him. If you expect him to ignore the constitution or you won't vote for him then you are utterly unamerican.
Trump reading from a prepared script looks a fool. In any debate he will splutter and waffle and lose track of himself before finishing a sentence (if he ever manages to finish a whole sentence).
You sure have some strong opinions on Biden. Being outside the country I haven't dug into the details so much but I'm still surprised at what you have to say. The few facts I've seen suggest his only problem is he is on the mild (read boring ) side.
What has lead you to arrive at your opinion of him? It would be interesting to see your facts and sources.
I'm an outside so I don't dig into the details at all since I'm not responsible for voting. My rough picture is that Trump is the worst thing that has ever happened to the US (and the rest of US). It seems to me that Biden would have to be pretty strangely bad to want to risk 4 more years of Trump.
But I haven't paid much attention to Biden. To me he is a bit unexciting and not as what some down there would call "radical" as I would like but I don't see anything particularly negative.
What is it that he has done that makes anyone willing to risk Trump?
