Obama set to win low-key primary race


It's official: Barack Obama will clinch the Democratic nomination for President tomorrow, ending a low-key primary race that many people probably didn't realise was happening.

Mr Obama is certain to reach the 2,778 delegates he needs when five states vote tomorrow. He has won almost every delegate so far, with few exceptions. But campaign officials say they are focused on the all-but-certain Republican nominee, Mitt Romney.
