Barack Obama and Mitt Romney were victorious in North Dakota's presidential caucuses.

Obama was the winner over Hillary Rodham Clinton on the Democratic side.

Romney prevailed over front-runner John McCain, an Arizona senator, as well as Ron Paul and Mike Huckabee.

With 100 percent of the GOP vote counted, Romney beat McCain 36 percent to 23 percent. Paul had 21 percent and Huckabee finished with 20 percent.

Meanwhile, with 25 of North Dakota's 47 precincts reporting, Obama had 5,453 votes, or 58 percent. Clinton had 3,717 votes, or 40 percent. The remainder went to John Edwards, Dennis Kucinich, Mike Gravel and a handful of write-ins.

Republicans packed into the Bismarck Elks Lodge in Bismarck tonight to vote for their favorite presidential candidate. The building was so jammed that GOP leaders asked people not to hang around after voting -- so others would have space.
