"Electioneering for the BBMP polls virtually concluded on Thursday late night with the 66.19 lakh Bangalore electorate getting set to vote on Sunday. Technically the candidates had time till Friday 7 am to end their campaign, but with the ban on using the public address system after 10 pm, the candidates had to close shop on Thursday night." See the TOI article here.
The campaign has been very vigorous. The door to door campaign has been very good with distribution of election ID of each voter in a house hold. I have got this info from both BJP and the congress.
