(CNN) - New York Sen. Hillary Clinton claimed the biggest prize of Super Tuesday's Democratic primaries with a win in California, CNN projected, while Sen. Barack Obama rode high in the Midwest and Rocky Mountain states.
Clinton took a strong early lead in California, with exit polls finding extensive support for the former first lady from women, Latino voters and blue-collar Democrats concerned about the economy. A total of 441 Democratic delegates will be chosen from the state, divided proportionally under party rules.
More than four-fifths of the 2,025 delegates needed to clinch the Democratic presidential nomination were at stake in contests across 24 states and American Samoa, but neither candidate appeared to land a knockout blow.
California - where 441 Democratic delegates will be chosen - was the biggest prize of the night, and exit polls indicated a close race between Clinton and Obama there. As polls closed on the West Coast, Clinton congratulated Obama and said the campaign would go on.
Clinton, the former first lady, was forecast to win her home state and neighboring New Jersey - as well as Massachusetts, where the state's two senators and governor had endorsed Obama.
