Clinton wins Nevada Democratic caucuses

Sen. Hillary Rodham Clinton won the Nevada caucuses Saturday, powering past Sen. Barack Obama in a hard-fought race marred by last-minute charges of dirty politics. The victory marked a third-straight campaign triumph for the former first lady, who gained an upset victory over Obama in the Jan. 8 New Hampshire primary and the largely uncontested Michigan primary last Tuesday. Early returns showed the former first lady gaining roughly half the vote in a three-way Democratic race, with Obama at about 45 percent and former North Carolina Sen. John Edwards placing a distant third.
