In the demographically colourful and historically significant Chandni Chowk constituency, a blockbuster contest is in the offing among Congress' Kapil Sibal, BJP's Harsh Vardhan and AAP's journalist-turned- politician Ashutosh to win the prestigious seat. Though traditionally a Congress stronghold- the constituency is expected to witness division of Muslim votes between AAP and Congress that may help Vardhan, who was chief ministerial candidate of the party in the December assembly polls. With a significant 20 per cent Muslim voters out of total of 14 lakh electorate, all the three candidates are going out of the way to woo them though they deny seeking votes in the name of religion, caste and community.
