Obama overtakes Clinton in race for super-delegates

Barack Obama has eclipsed Hillary Clinton for the first time in endorsements from super-delegates, who could tilt the balance in the close nomination contest. During the weekend, four super-delegates pledged to support Obama, including two who previously supported Clinton, the former first lady. Obama, 47, who hopes to be the first African-American US president, now has 275 super-delegates to Clinton’s 271, US media reported. Obama already has 1,864 delegates from party conventions and Clinton has 1,697. He is just 160 delegates short of the 2,025 needed to secure the Democratic Party nomination.
