When Indian Muslims go to vote, they have only one aim in mind--to defeat BJP.
For a long time after Independence they voted for Congress, as Congress leaders told them " If you dont vote for Congress, Jan Sangh ( now BJP ) will eat you up ". So they voted en masse for Congress.
After demolition of Babri Masjid in December 1992, Muslims became angry with Congress, and broadly joined Mulayam Singh in U.P. and Lalu Yadav in Bihar. But then too they resorted to 'tactical voting', i.e. voting for the strongest non BJP candidate in a particular constituency. So in some constituencies they voted for BSP, Congress.etc
In Delhi at one time there were only 2 strong parties, BJP or Congress. Obviously Muslims would not vote for BJP, and so they voted for Congress. When Congress became discredited and AAP was formed, they became AAP supporters.
And now that AAP too is discredited, where are the poor Indian Muslims to go ?
