I am not in the US and struggle to understand why things work the way they do but it seems large parts of the country are impossibly conservative in ways that outsiders simply can’t comprehend. Things that seem like common sense to everyone else can’t happen there for very deep cultural reasons that aren’t in the normal experience of people in other western democracies. They depend on their Supreme Court to decide law on things that elsewhere are determined by legislation because any politician taking a political stance is painting a target on themselves. It doesn’t seem like an environment favorable to young leaders who want to make a difference.

The country was broken by electing a man with brown skin and the thought of electing a woman after sent them firmly down the path to Christian nationalist fascism. Not sure I would want to see how they react to a young candidate. I imagine it would be savage. I think the age of the president is by far a lesser concern than their executive team and policies and given both are extremely old and with very obvious health issues they cancel out so people should focus on more important differences.
