(CNN) - New York Sen. Hillary Clinton claimed wins across most of the Northeast in Super Tuesday Democratic presidential primaries and split Deep South states with Illinois Sen. Barack Obama, according to CNN projections.
CNN forecast Clinton, the former first lady, to win her home state and neighboring New Jersey - as well as Massachusetts, where the state's two senators and governor had endorsed Obama.
She also was forecast to win primaries in Arkansas - where her husband was governor for more than a decade - and neighboring Oklahoma and Tennessee.
CNN projected Obama would win primaries in Delaware, Connecticut and Illinois, which sent him to the U.S. Senate in 2004. And he notched up substantial wins in heavily African-American Georgia and Alabama, despite extensive support for Clinton among black officials in each state.
The contests spread into the northern Great Plains as the evening went on, with Obama heading for wins in Democratic caucuses in North Dakota and Kansas.
