( dpa ) - Democratic presidential candidate Barack Obama, 46, was projected to win the Georgia state primary ahead of rival Hillary Clinton, 60, the three main US broadcasters reported Tuesday.
The state remained up for grabs among Republicans vying for their party's nomination. John McCain, Mitt Romney and Mike Huckabee were all still in contention, according to CNN, MSNBC and FOX.
Official results had yet to be released after polls closed at 7 pm (0000 GMT). A total of 103 delegates are up for grabs in the state for Democrats, 72 for Republicans. MSNBC reported a 35-delegate difference in favour of Obama.
Obama, hoping to become the first African-American president, had been expected to win in Georgia, the largest southern state voting in Super Tuesday. The Illinois senator won neighbouring South Carolina last month by a more than 2-1 margin ahead of Clinton.
About 50 per cent of Tuesday's voters in Georgia were expected to be African-American. Nearly 90 per cent of them picked Obama, but 39 per cent of whites also voted for him - a sharp increase from South Carolina - according to exit polls from CNN.
