Sonia made great sacrifice in 2004 (She was not eligible for PM of India is different matter). Lot of congress leaders in Karnataka from Krishna to Sabhapathy in Udupi are making great Balidaan. (They knew that congress is headed for washout and why suffer in saffron surge).
Now is the time for Communists and other (pseudo) secularists to make great sacrifice for (pseudo) secularism. Communists will give 50 percent of seats in kerala and Waste Bengal to congress to help it survive. In saffron surge congress is going to get wiped out in Karnataka, Madhyapradesh, Rajasthan, Delhi, Chattisgarh and next years loksabha election and in Maharashtra. People will hail this revolutionary sacrifice of communists.
