Rishi wants to know how I can claim that the Presidential System underdelivers change, and Ritwik angrily objects to my claim that in the Parliamentary System, the Prime Minister can handpick legislators. Both of them have missed an important qualifier: popular.
Change is rare in any mature democracy. This is as it should be. Obviously, I prefer change in the direction of less government and limited powers and others may prefer otherwise, but whatever the direction of your preferred change, I think that we should be wary of a system where a Chief Executive can, on the basis of just one election, bring about fundamental and drastic change in the structure of the polity.
