The massive victory of the Aam Aadmi Party (AAP) in Punjab was not a result of any specific caste or community backing it; rather the party garnered votes from all the castes and communities.
The data from the Lokniti–CSDS post–poll survey in Punjab confirm that the victory of AAP represents a bouquet of support from all castes and communities. With both traditional players, the SAD and the Congress, failing to muster much support, AAP and, partially even the BJP benefited among most major caste groups.
The Hindu upper castes, which used to support the Congress, have shifted their vote to the AAP and, to some extent, to the BJP; a little over one-third of the Hindu upper castes voted for the AAP and one-fifth for the BJP. The other section to shift on a large scale was the Hindu OBC voters.
