I've been doing some digging on the Puerto Rico caucus since I've seen conflicting info regarding whether it's winner take all or not. Now, officially it is proportional allocation, as seen at this link.
http://www.thegreenpapers.com/P08/PR-D.phtml#0607Historically, however, Puerto Rico has acted as a banana republic of sorts, allowing the governor to override the voters and give all the delegates to the candidate of his choice. It's amazing to me that this has been tolerated, but it has. As noted in this article, for example, Jesse Jackson won the Puerto Rico primary in 1988, but the Governor ended up giving all the delegates to Dukakis:
In 1988 Jesse Jackson won the primary in Puerto Rico over Michael Dukakis. Yet a month later, Puerto Rico's governor instructed his fifty-one delegates to back Dukakis. "This is clearly machine politics," Jackson wrote then, "and should have nothing to do with the 1988 campaign." The 2008 campaign has again exposed the undemocratic influence of the superdelegate elite. But just as the activists of '68 pushed aside the party bosses, forty years later voters can demand that the party's nominee reflect their choice.

http://www.usnews.com/blogs/barone/2008/2/6/puerto-rican-poll-power.htmlThis sorry history has led people to worry that the same will happen this year. The Governor of Puerto Rico Anibal Acevedo-Vila has endorsed Barack Obama (even though Clinton has big support there). It appears, however, that with the whole world watching, no such tricks will be played. In fact, in his press release endorsing Obama, the Governor noted, in apparent response to the US News article, that:
"The Commonwealth of Puerto Rico will hold its Democratic Presidential
campaign caucus on June 1, 2008, with 63 delegates available to the
candidates. Contrary to recent media reports, Puerto Rico's delegates are
awarded on a proportional basis."
http://www.prnewswire.com/cgi-bin/stories.pl?ACCT=104&STORY=/www/story/02-13-2008/0004755860&EDATE=The Governor thus seems to be assuring that the voters will actually decide this election (a quaint idea). Assuming that's the case, the Puerto Rico delegate scheme seems to be tailor-made for inertia. 36 district delegates are proportionally allocated by senatorial district (Puerto Rico has no congressional districts).
District 1 San Juan: 4
District 2 Bayamón: 5
District 3 Arecibo: 4
District 4 Mayagüez: 4
District 5 Ponce: 4
District 6 Guayama: 4
District 7 Humacao: 4
District 8 Carolina: 4
As you can see, all but one of these districts has 4 delegates, which means that Hillary will have to get more than 62.5% of the votes in a district to avoid a 2-2 split. Presumably, the Governor's political machine will have enough influence so his friend Obama is not blown out by such margins. Since the Puerto Ricans voted for Jesse Jackson in 1988, this speaks well for their ability to vote for a black candidate. There are also 19 at large delegates which will be allocated based on the total PR vote.
In its projections leaked accidentally (?) to the media, the Obama campaign anticipated that Hillary would get 30 delegates and Obama would get 25:
