Minority Voters Push Hillary Clinton to Victories
Hillary Clinton took full command of the Democratic presidential race on Tuesday as she rolled to major victories over Bernie Sanders in Texas, Virginia and across the South and proved for the first time that she could build a national coalition of racially diverse voters that would be crucial in the November election.
Based on results from Democratic primaries and caucuses in 11 states, Mrs. Clinton succeeded in containing Mr. Sanders to states he was expected to win, like Vermont and Oklahoma, and overpowering him in predominantly black and Hispanic areas that were rich in delegates needed for the Democratic nomination...
Mrs. Clinton was set to win at least 150 more delegates than Mr. Sanders from Tuesdays states; the final delegate allocation will be determined in the coming days. That outcome would give Mrs. Clinton a bigger lead than Mr. Obama eventually established in 2008, which she was unable to overcome. The delegate haul resulted from a broad cross-section of support for Mrs. Clinton: In Alabama, Georgia and Virginia, blacks accounted for more than half the population in some districts, while Hispanics dominated many of the districts in Texas that allocated delegates on Tuesday. Mrs. Clinton had some of her best results in these regions, and also did well in largely white areas of the south.
