Senator Hillary Clinton defeated Senator Barack Obama, convincingly, in the Puerto Rico Primary - the 3rd to last primary election on the Democratic calendar.

Senator Clinton’s 68% to 32% victory, this late in the race, adds more intrigue to the last 2 primary races (South Dakota and Montana) scheduled to be held on Tuesday.

Puerto Rico’s Democratic Party moved the date of their primary from June 7 to June 1, according to an article in El Nuevo Día (Spanish-only). They also changed their method of selecting delegates from a caucus to a primary. Democrats in Puerto Rico will be deciding on 56 delegates — a higher number than 27 states — and could play a far more significant role in choosing a nominee than they have in years past. 

The date is being switched because election law requires Puerto Rico’s primary to be held the first Sunday of June, which is the 1st. The original date was a clerical error, and the DNC is expected to approve the change without any dispute.

So far, this decision hasn’t gotten much attention from the mainstream media, although it’s flitting across the blogosphere pretty quickly. I learned of it from Politico, who in turn got it from DemConWatch.
