The democratic party is united behind Biden. Even AOC and Bernie have endorsed his reelection.

Quibble. AOC and Bernie are united against Trump, and likely Desantis. I doubt either would have Biden as their first choice. They just realize the alternative is too horrible to contemplate.

I remember when I was proud to say I was a Republican. The Party has so lost its way, it is unrecognizable to me today. I'm sure there is someone somewhere within the Party that makes some sense, but he/she isn't in any spotlight. He/she is swamped by, well, the Swamp that is Republican effluent and nonsense. Which is a tragedy, because our system functions better if there is a credible opposition party. Until the nonsense abates, I don't even have to think about my vote anymore. It's just "D" at this point. Never thought I'd say that, but there it is. I hope that can change within my lifetime, but I'm not optimistic. Republicans just seem to double-down on the absurd. Which, when one looks at their sources for information, isn't really surprising. For every BHM, there appears to be 10000 "dittoheads" ranting and raving. (We may not agree on a lot of things, but at least we can have a conversation with BHM and a few others.)
