There is no question this is a likely outcome, however it is no more preordained than any other fact of political life. The strategic issue for serious activists is how to make sure that the kooks and nutters don't win out over those capable of rational discourse. As anarchist organizer (insofar as this is not an oxymoron) I would imagine you are in a good position to offer suggestions on how to prevent this. Whether you are not interested in thinking seriously about this will indicate whether you are more interested in promoting your ideological agenda than in achieving real albeit limited gains.

Of course, this is a different issue: i.e. how to prevent the party from having its fundamental objectives compromised by "responsible leadership" i.e. the usual suspects within the liberal intelligentia who also have no interest in offering a fundamental challenge to objective institutionalized power. Perhaps Nathan has suggestions along these lines.
