Challenges linked to elections come in many shapes and sizes—some can be anticipated, most are hard to tell. The ruling AIADMK in Tamil Nadu is now straddling both fronts. The party clearly anticipated that its vote-share would be eroded after its split and when T.T.V. Dhinakaran emerged as a doughty challenger. To compensate this erosion it embraced the PMK, BJP and Vijayakanth’s DMDK—even if it meant contesting only 21 seats as against all the 39 it had in 2014, of which it won 37.
