I always find it interesting that US parties don't have the concept of a leader of the party in the same way we do in the UK. Appreciate you have things like speakers, minority leaders and stuff like that but, for example, there's no equivalent to Kemi Badenoch for the Democratic Party. Would have thought that, if they did, then imposing a united identity would be much easier. I guess the answer is that it would interfere with the whole presidential primaries etc but parties in opposition in the US always look a bit of an aimless mess.
