Superstar Rajinikanth today tweeted his support to Prime Minister Narendra Modi's 'Swachhata Hi Seva' campaign. "Cleanliness is godliness," he posted amid speculation that he is a chief ministerial aspirant that the BJP would gladly piggyback on to win over Tamil Nadu. Rajinikanth's tweet came hours after fellow actor Kamal Haasan actually said he would like to be Chief Minister, "if required, even though it is a crown of thorns".
