Politics is impossible without parties. The problem is that we just have two very similar parties with an exclusive monopoly on power.
Why is it "impossible without parties"? (The concept "parties" here meaning
permanent parties)
Politics needs a stable, continuing organization to achieve long-term goals that will take longer than a single term in office otherwise we would have to depend on cults of personality built around charismatic individuals to provide a center for popular agendas.
Nah, I don't think so. If a long term goal is a worthy one, the impetus will (and should) come from We the People, pardon the nominative case. Once you start hiring the same guy to do a job that didn't get done you've wandered away from goal attaining and wandered toward "job security". If we have a goal and Pol A doesn't get it done, put Pol B in there. Same goal. Should be no different from hiring somebody to get a particular job done.
The job itself is the constant. That's not the goal of an Entrenched Political Party -- the goal of the latter is self perpetuation. Which as far as We the People are concerned, is profoundly irrelevant.
