The past mistakes (which is the mildest word to describe the communists policies of 1948 (B.T.Randive), during China war and also emergency) have led to communists getting limited to 2 states. Even in those states communists have hugely benefited from the effective alliances they have forged and also the absence of credible opposition and also an opposition leader. Once Bengal and Kerala can get a leader of Nitish Kumar's calibre (who could position himself as an alternative to Lalu), even those 2 states will slip out their hands. It is time they carefully read the principle of diminishing returns. Any comments?
