The BJP may be spending money like water for the Bihar elections, but party supremo Amit Shah has halved the bills of several public opinion survey companies. Such a company, on whom Amit Shah and Modi had the most faith, had raised a bill of Rs five lakh for Bihar Assembly elections, but the payment made was a mere two-and-a-half lakh. At the same time, Arun Jaitley, who is considered to be an expert on Bihar matters, got an agency conduct a survey for the party, but the agency is being paid even less than that.
