If not for the Muslim League

This is a follow up post to the previous one . I was just curious to know if the Congress Party (INC) on its own won a majority in Kerala in the last 30-years. If my numbers are correct, its a big NO

And what is more startling, its % of seats out of the total has been reducing - both for the "UDF winning cycle" (shaded in green) and for the "UDF losing cycle". And in the latest election, Congress party doesn't even have a simple majority in UDF itself -allies have. CongressMuktKerala in offing ?
