Without a majority vote, one can't come to power. So votes are required for the leaders to be in power. That is true always. If there is no support from the people, politicians can't go to power. Indian voters are very wise. They always select a person who is the best among the contesting persons. If the people are not happy with their leader, next time they will not cast their vote to that person. If they like him, even though he changes the party also, they will give him the vote. So the politicians should see that the voters are happy with him These days politicians know many tricks and they know how to win in the elections.
