Politics is always in the minds of people. it is inborn character even children sometimes use it. It is a behaviour pattern and used for personal benifit and gains. politicians are named politicians because they are the ones who use this behaviour pattern maximum. In politics everything is fair just like in love and war. A normal person must learn to defend himself when he comes to know that he is going to be used, please read chanakya. ALSO  use right to information so that many people can be saved from politics. Use your inner voice and vote ,ask for results and donot give much attention and praise to unworthy politicians.
