I don't think there is.
I think a person who should be in the running for president needs to have some name-recognition but also be non-polarizing which unfortunately is hard to find in combination. There are some names floating around like moving the candidacy to Kamala Harris, but... I feel like a lot of people don't like her. Which shouldn't matter but I think a lot of people base their voting on "would I enjoy sitting down at a dinner table with this person and could I speak candidly" and don't look into the actual political standpoints of that person, so likeability more than anything.
I'm not American, but I still feel a slightly vested interest in the outcomes of the elections because the outcome of the US election will shape global politics and even more than that in the next coming years, especially if Trump and his fascist cronies take control. But my point being is that I don't know every single name in American politics, but I would say your average American voter probably knows as much as me, and the names that people know about are usually the polarizing ones that wouldn't have a chance of winning. The Democrats are sorely lacking a strong candidate with a name that can rival Joe Biden in name-recognition without being polarizing.
Joe Biden is too old, but he has good people around him so I could see him doing 4 more years while doing MORE to find a good replacement for him would be the best thing for the US.
I swear to fuck I read "Voting machines" and I had to read three times before I got it right. Yet I would barely be surprised if that's a thing in a couple of years if Trump wins the election. "Vote for the Republicans, get a free bullet to kill a Democrat"
