Congress released its sixth list of 23 candidates late Saturday for the Rajasthan polls, dropping controversial minister Mahesh Joshi. With this, the party has declared nominees for 179 of the 200 seats in the state. Joshi was seeking a ticket from Jaipur's Hawa Mahal seat. He has been replaced by Congress city chief R R Tiwari. Tiwari, though, had filed his papers earlier in the day, even before the official list was issued. BJP has fielded a preacher, Balmukund Acharya, from this seat.
