Chadayamangalam retains the legacy of having elected Communist Party of India (CPI) candidates since 1970 except in 2001, when Prayar Gopalakrishnan of the Congress won the election. All the eight grama panchayats of the constituency were won by LDF in 2015 local bodies elections. In the 2014 Lok Sabha elections, LDF candidate M.A. Baby had secured a lead of 6,806 votes over his UDF rival N.K. Premechandran in the Chadayamangalam segment. The sitting CPI legislator Mullakkara Ratnakaran is once again in the fray as a candidate of the LDF.
