Political parties in democracy are quite literally labor unions. The people in them do not independently lead the state, they are merely employees, hired by the leadership. You know, that's what you host elections for — to choose which employee you want to hire from the set of candidates who want the job. They may act as sub-leaders within the capacity of their job, but they are not the top leaders we are talking about. "Leadership" here was never intended to be about "middle managers".

That seems pretty obvious, but perhaps this confusion is the source of your misunderstandings?

Done with what? Thinking other threads are related this one? That is a good idea.
