Ron Paul hoped a speech to North Dakota Republican caucus goers in Fargo could bring him the first state victory of his presidential campaign Tuesday. Rivals Mitt Romney and Rick Santorum waited to see whether their own North Dakota campaigning would pay dividends.

North Dakota Republicans prepared to visit one of 59 caucus sites Tuesday night to hear presentations about Romney, Paul, Santorum and Newt Gingrich, and to vote for one of them. All but Gingrich have campaigned in North Dakota.
