Indian National Congress has won two thirds of all elections in Wayanad since 1982, but in recent times all three assembly constituencies in the district are in play with LDF winning Mananthavady, Sulthanbathery and Kalpetta in 2006. Median margin in Mananthavady and Kalpetta are above 10% which is above average and shows clear waves and swings.
Palakkad is CPM's district and it's deep ties with working class delivers near two thirds of the seat in the left's account . Constituencies in Palakkad are Alathur, Chittur, Kongad, Malampuzha, Mannarkkad, Nenmara, Ottappalam, Palakkad, Pattambi, Shornur, Tarur and Thrithala.
Malappuram belongs to Indian Union Muslim League. There would be very few places in the country where elections are so one sided. It isn’t the fact that 14 of 16 constituencies swing UDF, but the median margin of victory and the unsurmountable lead Muslim league has in some of these places which is impressive.
Kasaragod leans LDF. BJP has a significant vote share in the district, it’s highest in the state, but this vote share has declined since 1982. Manjeshwaram still remains party’s best bet to open an account in 2016. Then that was the case in 1982, and every election since. Then BJP has struggled to go beyond the 20% mark.
Kannur is Communist Party Marxist’s citadel. A red fort with 8 of 11 constituencies not just leaning left, but near impossible to win for other parties. While subject to shockers like Azhikode in 2011, when CPM blew a 29 point lead, the district will side with the left. K.C.Joseph’s Irikkur and Kannur constituencies though buck the trend and side with UDF.
