T'puram: With the BJP announcing the candidature of Kummanam Rajasekharan in Thiruvananthapuram, it will be the only parliament constituency that gives all its candidates an equal chance of winning the triangular contest. As sitting MP Shashi Tharoor is set to seek a re-election for the third time and LDF candidate C Divakaran is posing a strong fight with his track record, it is not possible to predict if former Mizoram Governor Rajasekharan stands a chance in the constituency.
