Barack Obama said he would honor their vote.
The BBC reported:
Voters in Puerto Rico have supported a non-binding referendum to become a full US state.
The measure will require approval from the US Congress, but President Barack Obama has said he will respect the vote.
The island is currently a US territory, which uses the dollar and whose citizens travel on US passports.
But it does not return senators to the US Congress and is represented in Washington by a non-voting delegate.
Almost 80% of the island’s electorate took part in the referendum, the fourth in the past 45 years.
With almost all the votes counted, almost 54% voted to change the island’s relationship with the US.
And in reply to a second question on what future they favoured, nearly two-thirds wanted full statehood…
…A young voter in the capital San Juan, Jerome Lefebre, said: “Puerto Rico has to be a state. There is no other option.
“We’re doing okay, but we could do better. We would receive more benefits, a lot more financial help.”
The Democrats will love to hear that.
