Alappuzha, the Venice of the East, is the cradle of the Communist movement in the erstwhile State of Travancore. In the latter years, however, Congress had begun to punch above its weight in this district. It was the legendary K Balakrishnan, editor of Kerala Kaumudy and leader of the Revolutionary Socialist Party (RSP), who trounced Susheela Gopalan in 1971 to snatch the Alappuzha Lok Sabha seat away from the Left for the first time.
This period also coincided with the emergence of Congress Young Turks such as Vayalar Ravi and A K Antony in the land of the Punnapra-Vayalar revolutionaries. Ever since a 29-year-old V M Sudheeran retained the seat in 1977, Alappuzha has swung fairly evenly between the Left and the Congress.
