(CNN) - The Democratic Party of Puerto Rico has submitted a revised plan to the Democratic National Committee that would move its presidential nomination contest from June 7 to June 1.
The proposed plan would also change the contest from caucuses to a primary.
“This is an important mark in the political history of Puerto Rico,” said Roberto Prats, the territory’s Democratic party chairman, according to an account in the Spanish-language paper El Nuevo Dia.
The move would not become official until the DNC’s Rules and Bylaws Committee approves the new plan after a 30-day comment period.
If approved, the shift would make the Montana and South Dakota primaries on June 3 the final Democratic contests of the 2008 primary season, if Michigan and Florida do not hold repeat votes after that date.
A DNC spokeswoman confirms to CNN that the party has received the revised plan, and that the date change is likely to be approved, though official action won’t be taken for at least a month.
There are 55 pledged delegates at stake in Puerto Rico, and 8 superdelegates. Puerto Rico Republicans held their presidential nominating contest on February 24.
