Muslim population in these regions hovers around 20% with 30% in Lucknow. So most of the votes for BJP are from Hindus. There is too much stigma attached with the BJP actually so we don't vote for them. They and 'Modi are seen as responsible for the Gujarat genocide.
The good thing about muslims is we favour laws otherwise India would have been broken into a half once again. My mammoo who stayed on in Lucknow when I asked him about Modi's victory he said Modi is an elected representative of the Indian people and the courts found nothing against him. I pressed him further but he respected hindus actually which is actually an Ansari trait. Being half ansari do note no one will defend hindus more than us.
Anyway about Shias I think this is all incorrect information. In Kakori shias are the majority and rarely vote for BJP. Even patriotic Indian Muslims who refuse to acknowledge Pakistan's shared history of muslims will give the same opinion.
