As US Democratic Party Primary Season Winds Up, Each Election is Scrutinized

The U.S. Democratic primary contest is drawing to an end, and with just one month of campaigning left, candidates and political analysts are paying more attention to each remaining election.

Voters in North Carolina and Indiana cast ballots in Democratic primaries on Tuesday. Five more states -- West Virginia, Kentucky, Oregon, Montana, and South Dakota -- and the territory of Puerto Rico will hold primary elections by June third.

Each remaining ballot is seen as crucial in deciding whether the candidate with fewer committed delegates, Senator Hillary Clinton, will earn enough votes to stay in the race -- and whether the delegate-leading Senator Barack Obama can earn enough votes to win his party's nomination.

As of Tuesday, neither candidate had won the more than two-thousand delegates needed to secure the nomination.

The primary season opened on January third, when Iowa held its caucus.

Most of the delegates are allotted based on the outcome of state primaries or caucuses but 20 percent, known as superdelegates, are uncommitted and can choose either candidate.
