Rosa is probably not happy that she has to include the Militarists. Lenin is out, Rosa would never allow him to hold an office in her government. This means there's a chance the Leninists and Moderates will dissolve and join the Luxemburgists in a united Marxist faction. Sorel, despite being the peasant's choice fail to gain power, and thus his support might diminish and the peasants seek a new champion. Meanwhile some more hardline Marxists might be disappointed of Rosa's dominance, and there's a chance for a Maoist faction.
I think no. Maoism? That's a peasant ideology. M-L is far better (M-L, not the weak Luxemburgism). Moreover, if Luxemburg disdains M-L we could simply withdrew our support to her.
Worker's vote counted by Tony according to his secret formula. We voted for a Chairman, the Worker's voted for the seats in the Assembly.
I knew Rosa couldn't bring nothing good...
