The way the Congress treats its supporters is clear from the way they deceived the Left and the way they treated TRS. The support of the TRS was taken (in both the Centre as well as the State) and once it was clear that the Congress could manage without the support of TRS, they were just ditched. This is probably a lesson for the SP too. At present however, the SP has choosen to be oblivious of this fact. They will learn this lesson when it may be too late.
