Clinton's Puerto Rico victory was marred by low turnout
Hillary Clinton's win in the primary contest in Puerto Rico is unlikely to make a difference to Barack Obama's overall lead.
After Puerto Rico, he will only need around 50 delegates to clinch the Democratic nomination.
On Saturday, the Democratic Party committee voted to restore some of the votes from Florida and Michigan after the two states broke voting rules during the primary season.
But the Clinton campaign had hoped all the votes would be restored and says it's considering challenging the ruling.
Puerto Rico is a symbolic victory for Hillary Clinton, because she was always expected to win it, but even the wide margin of her victory there will not dent the overall lead of her rival Barack Obama.
As it is not a state, but a self-governing territory, Puerto Rico doesn't vote in the presidential elections so it will not make a difference in November.
Final primaries
But Senator Clinton is showing no sign of giving up the fight yet.
Obama was already campaigning for Tuesday's South Dakota primary
She insists that her lead in the popular vote, which was increased by Saturday's decision to count Florida and Michigan, gives her a mandate to continue the race for the Democratic party nomination.
That is also why she was hoping for a high turn out in Puerto Rico - but in the end it was actually very low.
The Obama campaign said they hope that the Illinois senator will clinch the nomination this week with the last two primaries being held on Tuesday in South Dakota and Montana.
Barack Obama has already said that in his view the general election campaign starts on Tuesday.
