Kerala heads into a high-stakes Assembly election with all 140 seats in play and the Left Democratic Front aiming for a historic third consecutive term. The central question dominating the campaign is whether the United Democratic Front can end LDF's long rule, even as the NDA eyes a make-or-break opportunity to expand its footprint in the state. With anti-incumbency concerns, governance debates and a sharp triangular contest between LDF, UDF and NDA, the Kerala polls are shaping up to be one of the fiercest political battles in recent years.
