Nationalist forces are all set to win both the seats. Bengali Muslim voters have supported the BJP in both the seats.
PTI noted that the results alone do not establish how any community voted.
Tamil Nadu: TVK keeps both seats it took from the AIADMK
Both Tamil Nadu seats, reserved for Scheduled Castes, fell vacant after their AIADMK MLAs resigned and joined the ruling TVK, which then fielded the same two people. In Madurantakam, K. Maragatham Kumaravel won 72,149 votes to DMK candidate I. Paranthamen’s 52,068, a margin of 20,081, South First reported. In Dharapuram, P. Sathyabama polled 66,841 against 57,370 for the DMK’s S. Suganya, a margin of 9,471. The AIADMK finished third in both.
TVK won 108 of the 234 seats in this year’s assembly election, IANS reported. South First reported that its strength fell to 107 after Chief Minister C. Joseph Vijay vacated Tiruchirappalli East, and that the two wins take it to 109, still short of the 118 needed for a majority. The government is supported by the Congress, the VCK, the Left parties and the IUML, according to South First, though the Left parties contested these bypolls separately and campaigned against TVK. AIADMK general secretary Edappadi K. Palaniswami accused TVK of trying to build a majority of its own by inducing opposition MLAs to join it, South First reported.
