As of to-day, the Congress is the only party that can carry the country forward because it has intellegentia required to plan for the country, provided they rid of DMK who only help reduce the popularity of the congress. DMK is a negetive party with only intention to instil Karunanidih's relatives in power. However the DMK will only last till Karunanidhi is around. So it is time they completely ignore DMK. If you recall, DMK was with BJP when they were in power because they wanted their people to be at the centre of power.
