It is important in a parliamentary democracy that ruling party fears and opposition expects change. Only conscious and unbiased voters can bring such attitude.
Change in ideology is better than change in Govt.One election costs thousands of crores to the public.

everything is perfect . all laws are good that to be followed . need is to change the manual power who is not responding perfectly to the laws and policies.
I think there is no need of change of government at center and the present government is doing a satisfactory job. When people feel the requirement of any change it will certainly take place through the method of election in times to come...
