How the rises of the vote share of small and new parties affect major political parties?
When even older and bigger parties run from pillar to post for an alliance with the major two parties in Tamil Nadu, smaller and newly formed parties have increased their vote share contesting alone in this election. Despite the landslide victory in Tamil Nadu the vote share of DMK has only increased less than 10 % form the 2014 elections. BJP's vote share has gone further down from its 5.5 % in 2014 to 3.66. It has become less than that of MNM and NTK. But that of NTK headed by Seeman has increased by 2.7 % from 1.1 % in 2016 to 3.8 in 2019.
