During the legislative assembly elections that place in Tamil Nadu during April 2011, Vadivelu vehemently campaigned for the Dravida Munnetra Kazhagam (DMK) and its alliance. During his public speeches, he predominantly condemned politician and actor Vijayakanth, whose party, the Desiya Murpokku Dravida Kazhagam (DMDK), allied with the opposition party All India Anna Dravida Munnetra Kazhagam (AIADMK), headed by Jayalalithaa. His allegations of Vijayakanth included him being a "drunkard". In a campaign speech in Tiruvarur, Vadivelu stated that "(his) only aim is to sweep out Vijayakanth's whole team and to campaign vigorously for DMK's victory". Vadivelu was criticised as being biased, only supporting a DMK-led victory for personal gains and not once mentioning anything against the official opposition, the AIADMK, or its leader. In a turn of events, the election was eventually successful for the AIADMK alliance, and Vijaykanth won his constituency by a considerable margin.
