Washington: Barack Obama has won a second term as US president, defeating his Republican rival Mitt Romney in a closely contested battle that seemed almost to close to call till the end.
Obama, who four years ago was elected as the US’ first African American president, won 274 electoral votes, four more than what was needed to win.
As celebrations broke out across the country, a victorious Obama tweeted: “Four more years.”
“We’re all in this together. That’s how we campaigned, and that’s who we are. Thank you,” said another tweet from Obama, the son of a Kenyan father and a white American mother.
Four years ago, Obama was elected as the US’ first African American president and he has now become the third consecutive president to retain office after George Bush and Bill Clinton.
His predecessor George W. Bush served as US president from 2001 to 2009.
William J. Clinton, better known as Bill Clinton, became president in 1993 and went on to retain his office till 2001.
Before him, George H.W. Bush had a single term from 1989-93.
His predecessor Ronald Reagan won in 1981 and then retained the Presidentship, with his term ending in 1989.
Three presidents before him – James Carter 1977-81, Gerald R. Ford 1974-77 and Richard M. Nixon 1969-74 – served single terms.
The norm is that no US president serves more than two terms.
