Voting for the second phase of Chhattisgarh elections will be conducted on November 20 and preparations are underway. With polling starting in 72 seats spread across 19 districts of Chhattisgarh, the curtain comes down on the state assembly elections on Tuesday where the ruling BJP and Congress are in a tough fight even as an alliance between Ajit Jogi and Mayawati is expected to disrupt equations. The first phase of polling in 18 seats in the Maoist strongholds on November 12 saw about 76% of the voters exercise their franchise.
