I only wish, if this could happen that Anna's party awins next election and comes to power and change the rotten political system we have in our country. Unfortunately it is not as easy as it sounds.
By floating a new party, the opposition votes will be further divided (it's simple mathematics) and congress will ride back to the power. By forming a new political party, Anna will be helping the congress indirectly as most people look for a stable government which no opposition party is in a position to provide.
