The Left is either grossly stupid or too smart. Either way it appears that they are carrying out the orders of China.
Karat has been the greatest entertainer - going back and forth and making empty threats. He is supported by D Raja. Of the lot, Bardhan talks some sense - at times. Yechury is another joker in the Red pack.
The Left has messed up West Bengal big-time. Buddha is (or was) the only hope. But even his wings are clipped by an adamant Karat. Kerala has also been given bad governance - all prosperity is due to the hard-working Mallus. Tripura will never see the light of the day.
So much for Left rule in these states. They are so pre-occupied with opposition to the US that they don't mind cutting the nose to spite their face!!
Let the electorate just not vote for the Left and completely ignore them. Fighting or even debating with them will only keep them in the limelight.
