Youre being too simple. Biden is old. He was old in 2020 and he will be even older in 2024. This is his weakness and it’s a major weakness. Right now, to-day, almost have of the democrats don’t want Biden to be the nominee because he is too old. This doesn’t mean he wasn’t a good candidate in 2020, it means republicans wasted their time attacking him with conspiracy theory and Internet nonsense that never even touched his support instead of his actual weakness which would have worked. Again, you missed that and continue to miss it.
Every day that goes by Biden is less and less likely to even run again, let alone be the nominee. You see Newsome positioning himself, Murphy, even Buttigieg has moved to Michigan and expect Polis to move more into the conversation.
Then there is Bernie who you don’t understand does not have the votes. He’s like gum on the bottom of your shoe. Maybe he appeals to you but not the democrat base, who are moderate to conservative.
