CONCORD, N.H. -- President Barack Obama won New Hampshire's Democratic primary.

Obama, running uncontested, cruised to victory in voting Tuesday.

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 Rodham 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.
