Reactions.
After the BJP emerged as the majority party in the election, Prime Minister Narendra Modi thanked the public in a tweet saying, "Gratitude to the people of India for the continued faith, support and affection for the BJP. This is very humbling &amp; overwhelming." The BJP's UP chief Keshav Prasad Maurya attributed the victory to Modi saying, "It is a Modi wave. The wave which started with 2014 Lok Sabha elections is continuing in 2017 and the momentum will go beyond the 2019 general elections." Congress vice-president Rahul Gandhi sent a tweet to Modi congratulating him for his party's victory, to which Modi replied, "Thank you. Long live democracy!" Modi was congratulated on the victory by U.S. President Donald Trump during a telephone conversation on 27 March 2017.
The "BBC" wrote that the BJP "appears to have successfully forged a coalition of upper, middle-ranking and lower castes to be able to manipulate the social arithmetic of Indian elections". It also noted that the party successfully avoided the image of "doling out reckless patronage to a caste or group", which the BBC considered responsible for the SP's defeat. Bhanu Joshi of Delhi-based think tank Centre for Policy Research said, "He [Modi] has managed to go beyond the caste arithmetic. On the ground, the BJP is not perceived as a casteist party."
Political scientist Milan Vaishnav felt that the election "represents a referendum on demonetisation". Vaishnav said, "Whether voters were bothered by the implementation of the policy or not, they clearly have decided that the PM is a man of action."
BSP Leader and former Chief Minister Mayavati claimed that the BJP tampered with the Electronic Voting Machines (EVM) thereby rigging the election outcome. However, this charge was rejected by the Election Commission as well as other parties as lacking any substance.
