I think neither Prachanda nor Baburam will accept any post in the interim government. They still influence the interim government since it would be formed from the parties and must be run be the parties, so post or portfolio is not important to these duo at least for now. Instead, any other leader such as Suresh Ale Magar or Matrika Yadav can join the government representing Maoists. What is most plausible is that these duo leaders who mainly form their policies/idealogies will continue their campaign because they need to train their cadres who only know how to live in the jungle and fight with security personnels, so that those cadres/gourillas could also speak in language of politics to ordinary people/SPA activists. It is important to them since if there is any big mistake from maoists side while treating the people/parties, it may severely hurt the interests of their party. Besides transforming their cadres to politicians who can easily compaign for their interests in constituent assembly election, these duo must also convince their party cardes/gourillas/well wishers who were fighting for communist republic that they are not compromising a lot by going for CA to set democratic republic.
