Firstly I want to tell you that forums>bengal forum>google adsense is not the proper forum category for this thread so please notice these minor things so interested people can find threads of their interest with ease in the right category.
As for your title I do not agree with it because I think we need to first think if the current government is working or not and if it's actions are for the benefit of the people of west bengal then there is no change needed. If we see that scope for improvement is there then we can think of a change. I think that a healthy competition can always be beneficial if it makes ruling party work harder. My point is we cant pre-determine these things without seeing the results first.
