Modi-Amit Shah plan, to enter Chennai politics, appears to be successful, in the wake of Dravida Munnetra Kazhagam (DMK) chief Karunanidhi, withdrawing his intention to oppose demonitisation. It is said that he is walking the same path as Nithish Kumar in Bihar. Another clear indication, is the sudden return of Stalin, from America, to meet Modi. The Prime Minister (PM) has met Karunanidhi recently and has urged him to stay in his official residence. While BJP needs an alliance with DMK, the latter needs BJP to come out of the various cases in which some of its leaders are involved.
