After Tuesday's votes, only six contests will remain in the race for the Democratic nomination [AFP]

Tuesday's other contest in the state of Indiana is still too early to call.
 
The two states are the last big-delegate prizes left in the long race for the Democratic presidential nomination.
 
With a combined 187 delegates, Indiana and North Carolina are the two biggest primary contests left in the Democratic voting calendar in the run-up to the party's national convention in August.
 
The candidates clashed a day earlier over Clinton's plan to suspend the federal vehicle fuel tax, with Obama saying that his rival's proposal to suspend the levy over a holiday period was a "stunt".

As per Democratic party rules, delegates up for grabs on Tuesday are shared out according to the proportion of the vote received by each nominee.

Each nominee requires 2,025 delegates to secure the nomination to run for the US presidency.

With neither candidate likely to reach 2,025 delegates by the final primary vote in June, the contest is likely to be decided by superdelegates – high-ranking Democrats that can vote for their preferred nominee regardless of primary and caucus results.

From contests held so far, Obama holds 1,746 pledged delegates to Clinton's 1,611, according to MSNBC figures, including superdelegates who have already pledged their allegiance to the candidate of their choice.

After Tuesday, only six state contests will remain.

The 16-month battle between Clinton and Obama has raised concerns in the Democratic party that it will appear disunited to voters ahead of the November general elections.
