Delhi Polls: Here's why BJP focuses on slum dwellers

In the Delhi assembly election campaign, the BJP has been talking about 'home in place of slum'. Party workers are going to Delhi's 376 slums and promising families of building 2-room houses after the elections.
There are about 2 lakh families living in clusters in the national capital.
As part of its campaign, the BJP is going to the slums and saying that even though Kejriwal did not fulfill the promise made in 2015, the Modi government will build pucca houses for all the slum dwellers in the capital.
