Yeah, Biden is just the leader of his Dems faction. Like Trump is the leader of his MAGA Republicans, but not the whole nation.Current "leader" my eye.
There used to be a certain mystique about being president; I think that's what Confederate Soldier is really talking about. And they tried very hard, a lot of them (not all!! Look at Andrew Jackson, whom Trump most resembles.) to be neutral and indeed to "lead" all the people, or some from both parties at once, anyway. JFK, for instance, although his party certainly stole that election in Chicago as is well known; it DOES happen and we have to keep election stealing from happening as a regular thing.
