President Barack Obama has won New Hampshire's Democratic primary.
Far fewer voters participated in the Democratic primary than the competitive GOP primary, which was also being held on Tuesday.
Obama won New Hampshire in the 2008 general election, but he lost the Democratic primary four years ago. Hillary Clinton's narrow defeat of Obama, a dramatic upset coming after Obama's victory in the Iowa caucuses, led to a protracted race for the Democratic nomination.
Mitt Romney was projected the winner of the New Hampshire Republican primary Tuesday, with Ron Paul expected to finish in second place.
There were 13 other candidates on the Democratic ballot Tuesday. The sample ballot below shows the Democratic candidates listed, via the New Hampshire Secretary of State website:
