In February, Nebraska Democrats held a caucus. Not only was it the first time the party held a presidential caucus in the state, it's also the earliest they've picked a nominee.

"The Democrats decided to hold the caucus February 9th thinking they would be more influential, it would motivate the candidates to come to the state, and obviously that did happen," said Joan Blauwkamp, UNK associate professor of Political Science. 

Barack Obama was awarded 16 delegates to Hillary Clinton's eight, based proportionately on the state's popular vote. However, in some ways the plan backfired. In a tight race for the Democratic ticket, the candidates are stumping harder in the states that have yet to cast their votes. Also, fewer delegates are awarded to states that hold their contests earlier.  

"The party has been trying to provide an incentive to do less of that; to not make it so early and drag out the nominating phase of the election," Blauwkamp said. But that's exactly what's happened. With no nominee just six months before the general election, Democratic National Committee Chairman Howard Dean has asked the superdelegates to quickly make a decision.

"After Howard Dean came out and said that, and with some of the negativity going on from the campaigns, I thought let's just get this done now," said Audra Ostergard, superdelegate and Nebraska Democratic First Associate Chair.

Nebraska's now the only state with all of its superdelegates pledged. That's six votes in addition to the 24 rank-and-file delegates. The Republicans get 33 delegates. There's only one candidate expected on their May primary ballots, but there's still incentive to vote.

"John McCain has the majority of the votes he needs, but that's not the only race that's going on," Blauwkamp said.
