Puerto Rico initially planned to hold caucuses, as was done in 2000 and 2004, on June 7, 2008. In December 2007, a typo in the plan was discovered; the caucus date should have read June 1, 2008. Puerto Rico also decided to conduct a primary, rather than caucuses.
Puerto Rico has 55 pledged delegates which will be alloted on a proportional basis and 8 unpledged “superdelegates“. Puerto Rico will select 1 Unpledged add-on delegate. Selection of the unpledged add-on delegate will occur at the Assembly of the Democratic Party of the Commonwealth of Puerto Rico on June 21, 2008 in San Juan. As of April 30, 2008, 4 superdelegates had announced support for Sen. Hillary Clinton and 2 had announced support for Sen. Barack Obama.
In a poll conducted from March 31-April 5, 2008, Clinton leads Obama by 13%, holding 50% to his 37%, with 13% undecided and a margin of error of ± 4.4%.
