Hundreds of people with ties to India gathered in Edison, N. J., on Wednesday night to watch the initial election results trickle in, and celebrate a potential win for Mr. Modi, a leader whom many see as strengthening India’s image in the world.
The crowd, a mix of expatriates and American citizens, posed for selfies with a cardboard cutout of the prime minister, and cheered each time results favoring Mr. Modi’s B.J.P. were announced.
“There’s a more heightened interest this year,” said Krishna Reddy Anugula, 50, president of Overseas Friends of the B.J.P. The organization has about 4,000 members across the United States.
“People saw that this is a leader who is doing good for the country,” said Mr. Reddy, citing Mr. Modi’s economic proposals and pledges to improve the lives of the poor.
Indian-Americans — a population of about 4 million — cannot vote in the election unless they still retain their Indian citizenship. Then, too, citizens must be in India to cast their ballots.
Yet many Indians in America have sought to participate by organizing rallies, and calling friends and family members in India to encourage them to vote.
“Let’s elect them for five more years and see what they do,” Mr. Reddy said of the B.J.P.
