AAP leader Raghav Chadha has predicted a "historic and decisive" win for the INDIA bloc in Thursday's Chandigarh mayoral election, and billed the INDIA vs BJP contest as the perfect curtain-raiser for the Lok Sabha election due in April/May. "This will be an election where, for the first time, it will be INDIA vs BJP. After this election, the scorecard will be INDIA 1 - BJP 0," he declared.
