Chemistry has triumphed over poll arithmetic, Prime Minister Narendra Modi said Monday, profusely thanking Varanasi voters for electing him by a huge margin in the Lok Sabha elections. "Political analysts will have to accept that beyond poll arithmetic there is a chemistry," he told party workers on his first visit to his constituency after his resounding victory which was by a higher margin this time. The prime minister said he was also grateful to his opponents who fought against him. At the same time he lamented there was a sense of political untouchability, adding BJP workers were being killed for their ideology in West Bengal, Tripura and Kerala.
