I think it's a mistake to dismiss Trump in this way. I see Biden as a very safe and strong choice. Trump was extremely well-liked by his base. I think he is the most magnetic candidate that Republicans have fielded since Regan.
It took a huge effort, a strong and widely palatable candidate, a safe platform, a great campaign, a pandemic, mail-in voting, all the pooled power of the tech companies, and a lot of luck to take him down. Seeing how difficult it was just cements it for me that I am in a bubble and that tens of millions of people have very different worldviews and values than I do. It is very hard to admit to myself that my core values might not be widely shared by others.
