"Much of Narendra Modi's legitimacy among the Indian public comes from the perception that, unlike most of the political class, he is personally beyond reproach when it comes to financial corruption. Moreover, it was he who declared a war on corruption, the most emphatic example of which, the government claims, is the demonetization exercise. But Mr. Modi's silence on the corruption story finally exposed the hollowness of the government’s crusade against corruption, which in any case, has so far amounted to nothing more than targeted attacks against rival politicians. In politics, perceptions play a huge role. This is the first time that Mr. Modi's carefully crafted image as incorruptible and as a crusader against corruption has taken a considerable beating. WhatsApp messages, tweets and Facebook posts were rife with jokes about Mr. Shah’s businesses, and Mr. Modi’s silence. As examples from history show, when jokes start circulating about a powerful leader, cracks in political legitimacy begin to appear."
