This type of mockery of democracy, betrayal etc,. or repeated by these politicians over a period of time, Because they dont care about the wasteful expenditure incurred in conducting elections which otherwise could be used for some developmental project. This problem mainsly arises when people give fractured verdict in some states repeatedly as in the case Goa and we see a drama and change of Govt every after three months. A solution to end this menace of shameless and unpatriotic act of criminal politicians is that any agreement of support and alliance should be signed in the presence of Governor, and supporting party and MLAs/MPs should give an undertaking that the they will support the govt for a full term.Violators of such agreement should be permanently disqualified from contesting any more elections. As of now no party will like to bring in such legislation because Cong itself did this act in the case Charan Singh and Chandrasekar at the centre.
