Sen. Hillary Clinton made a blunt appeal to North Dakota delegates to switch their support to her, despite the fact that Sen. Barack Obama handily defeated her in the state's caucus in February. In an indication of how tense the battle has become for each Democratic delegate, Obama abandoned the campaign trail in Pennsylvania and scooted to North Dakota for the state party's annual dinner last night, despite the fact that he's already won 14 of the state's 21 delegates as well as six of the state's seven superdelegates.
The two candidates also will battle for votes tonight in Butte, Mont., when Democrats there hold their annual dinner. The Montana primary, which offers only a handful of delegates, is scheduled for June.
