In Bihar's Rajgir assembly constituency, 100 kilometres from Patna and in the home district of Chief Minister Nitish Kumar, Rajkishore Prasad and Sanjay Kumar Yadav are busy dissecting the day's newspaper, seated some distance away from a railway line. They are trying hard to make sense of the political events in the last few days that saw Nitish Kumar ditch ally Lalu Yadav for the BJP. They are so engrossed they almost fail to notice when a train passes by.
