The economic problems Kerala & its govt face have all been there for a while & nothing new. Karunakaran was becoming too big for the party; the political dramas that were staged by him with his son & daughter are too fresh in the people's mind & has only done damage to the party; And since no one will doubt Left will come to power next year as the routine 5 year power rotation continues in Kerala, it was the right time for the party to show him the door and groom some fresh alternative to the Karunakaran-Antony leadership. Chandy happens to be the most popular man at least within the Congress party in Kerala for the Cm's job at the moment.
