By the final count, Clinton had gained 68% of the vote to Obama's 32%, though analysts pointed out that the primary had an uncharacteristically low turnout.

Following the win, Clinton announced that she was winning the national popular vote. This statement, however, is contested as it includes the controversial votes from Florida, a state neither candidate campaigned in, and Michigan, where Obama's name did not appear on the ballot.

Even in defeat, Obama was on track to gain at least 14 delegates, bringing him within 50 of the 2,118 needed for the nomination.

Citizens of the commonwealth island cannot vote for president in the general election, but they can vote for nominees.

Puerto Rico was originally going to host eight caucuses but in March 2008 a decision was made to switch over to a full primary.

Hillary Clinton and Barack Obama support the idea that the citizens of Puerto Rico should decide for themselves whether they remain a commonwealth province or become a state. The topic is a major debate with the people on the island.
