An hour after sunrise Thursday in India, the world's largest exercise of democracy got underway. That's when polls opened on the first day of voting in Indian elections.
India is the world's largest democracy, with a population of 1.3 billion. Of that, nearly 900 million people are eligible to vote. There are 543 parliamentary seats up for grabs, including that of Prime Minister Narendra Modi, who's running for a second term.
But it's not a single-day affair. Poll workers must reach voters from the Himalayas to tropical islands in the Indian Ocean. So voting is done in seven stages, over more than five weeks — through May 19. Then votes will be counted on May 23.
Who is running?
Modi is the frontrunner. He and his ruling Bharatiya Janata Party, or BJP, are running for another five-year term. The BJP is a Hindu nationalist party that's brought India's majority Hindu faith into politics and public life in unprecedented ways. Under the BJP, many Indian states have banned beef, because cows are sacred to Hindus. They've revised school textbooks, and changed the names of Indian cities with Muslim-sounding names. Modi has campaigned as a pro-business, anti-corruption candidate, and he sought to portray himself as a safe pair of hands during recent violence with neighboring Pakistan.
Modi's main challenger is India's main opposition party, the Indian National Congress Party, and its leader Rahul Gandhi (no relation to India's freedom leader Mahatma Gandhi). Congress is a secular, socialist party that's pledged to protect India's minorities and improve life for the poor. It's a dynastic party; Gandhi's great-grandfather, Jawaharlal Nehru, was India's first prime minister. The party has been run by his descendants ever since, and it's dominated Indian politics until only recently.
If Modi wins and serves a full second term, it would be the longest stretch of non-Congress rule since India's independence from Britain in 1947.
What are the issues?
Many voters see this election as a referendum on Modi's past five years in office. India's economy is one of the fastest-growing in the world. But unemployment has hit a four-decade high. Crop prices are low, which means food is cheap. But it also means farmers' profits are meager, and they've been protesting in the streets. Voters also care about national security, after India and its archrival Pakistan — both nuclear powers — exchanged airstrikes this winter.
How does voting work?
Indian law says no one should have to travel more than two kilometers (about 1.25 miles) to vote. So poll workers have fanned out across the country, setting up polling stations wherever there's even a tiny settlement. They trek through the jungle to bring voting machines to a man who lives alone in a lion-infested forest in the western state of Gujarat, and climb to nearly 15,000 feet above sea level to set up a polling station for 12 residents of a village in the northern province of Leh.
All voting is done by Electronic Voting Machine, or EVM. The tabletop machines look like a miniature piano keyboard, with buttons next to a list of political parties, and also symbols — for those voters who might not be able to read. The machines fit into small suitcases, which poll workers have carried across glaciers, and through deserts — even hoisting them overhead as they ford rivers to reach voters. Some poll workers have to take helicopters to reach remote settlements of voters.
By the numbers
1 in 8 = Proportion of human beings eligible to vote in Indian elections
543 = Seats at stake in the lower house of India's parliament
272 = Seats any party needs, outright or by coalition, to form a government and choose India's next prime minister
2,293 = Political parties, national and local, contesting Indian elections
8,000+ = Candidates running for Indian parliament
2 = Anglo-Indian seats in India's parliament. Those are seats reserved for members of the British community who stayed behind in India after the end of colonial rule.
1 million = Polling stations set up across India
11 million = Government employees deployed to oversee Indian voting
3.9 million = Electronic Voting Machines (EVMs) in use
1991 = Year EVMs were introduced in India
At least $345 million = Value of cash, drugs, alcohol and goods confiscated so far from politicians attempting to bribe voters with gifts
15,256 = Feet in elevation above sea level of India's highest-altitude polling station in Tashigang, a Buddhist settlement near the Chinese border
66% = Voter turnout for the last Indian elections, in 2014
$5 billion = Cost of 2014 elections; this year is expected to exceed that
300 million = Estimated number of Indians on Facebook. This is the social media site's largest market. The Indian government has expressed concern that fake news, spread on Facebook and the phone messaging app WhatsApp, could sway voters. Facebook says some 40 million rupees (half a million dollars) has been spent on political ads in India so far.
