my original comment was aimed at the change in the constitution of the SA. One which you interpreted as "grabbing power".
The stated aim of the CC and the membership was completely the opposite. They believed, rightly or wrongly, that a "mass party" was possible. Therefore, should not be hamstrung by organisations of one man and his dog and that a constitution that allowed such a situation, would be a barrier to building a mass party.
The CC and the membership 'manoeuvred' to ensure, any constitution would not pre-empt a discussion with a mass membership of the shape and form that Alliance should take. IE SWP voted against disarming the police.
The prize wasn't control of a political nonentity, the Socialist Alliance as it was, but are significant minority influence amongst a real working class mass organisation.
The SWP, every political party/organisation/ grouping tries to win the vote for what they think be best for the movement. I don't see anything wrong with that.
