While some BJP leaders have called the Congress a 'barat' without a groom, people of a village in Tonk mounted Sachin Pilot on a mare on Saturday.   The state Congress president is making his debut in assembly polls from the Tonk constituency in the December 7 Rajasthan assembly election. While campaigning, he was stopped 100 metres from his meeting venue by hundreds of people from Chaan village and urged to mount the mare to cover the distance.   Accepting their request, he rode the mare for a few metres and then walked down to the venue, with the villagers playing dhol, bursting crackers and shouting slogans. At the venue, a number of women tied rakhis to Pilot.
