The Left parties should have used thier discretion to choose the lesser of the two evils. Nuclear deal vs catalysing dirty politics. How is Mr. Karat sure that people know the right thing - the situation the erupts after election is unpredictable. Dirty politics was played by all sides - Left cannot act inoccent - they triggered this by taking sides. You cannot expect the winner to take a moral stand and retire from the situation. The games is to be played by the applicable rules. Don't cry foul when you lose.
