Rajasthan Deputy Chief Minister Sachin Pilot on Wednesday said the Congress is studying reasons for its defeat in parliamentary elections by conducting surveys at booth levels.Speaking to media in Pradesh Congress Committee office, he said, "We have asked for reports from around 50,000 booths in the state to know how many votes we got and what led to the party candidates' defeat. After collecting data from booth level, we will conduct surveys," he added.Pilot said Congress got fewer votes across the country much against the party's expectations. "We need to find out reasons from the very base level. We will soon bring out a roadmap after evaluating all these reasons. Civic elections are coming up in the state and we have started making preparations," he said.Two by-elections are due in the state -- in Nagaur and Mandawa -- as two MLAs, Hanuman Beniwal and Narendra Kumar, resigned on Tuesday after being elected as MPs.
