Don't worry! In polit(r)ic(k)s there are no permanent bed fellows. Elections are round the corner. Hence realignment of forces is bound to occur since every party will make a Strength/ Weakness/Opportunities/Threats (SWOT) analysis of their own party as well as their bed fellows. KK must have felt that PMK will be a liability and hence deserted the party. Do not forget that he came out of Vajpayee govt before elections.
