Obama has clinched the Democratic Party’s nomination, CNN projects.

NEW YORK (CNN) – Sen. Barack Obama has clinched the Democratic presidential nomination, CNN projects as polls in the South Dakota primary closed at 9 p.m. ET.

CNN still has not projected a winner in the South Dakota primary, but based on exit polls and raw vote estimates the Illinois senator will receive at least five pledged delegates from this primary, enough to put him over the top. CNN also estimates that rival Hillary Clinton will receive at least five delegates from the South Dakota primary.
