A Democratic nomination question for anyone who knows.

Why do we give Puerto Rico such a comparatively large part in our Primary? It seems counterintuitive, given that they are so strongly against the statehood that would allow them to count in the GE. It also bothers me just a little when I see that there are states who have less say in the process.

I am interested in both a historical(how/when) did it start, as well as a modern perspective(why it continues).

I ask because I am genuinely curious. Its something that was not addressed in any history class I've yet had. My question would apply equally to Guam, in fact. It makes more sense to include DC. They want in, they want representation, they want to participate. But I do not see that in my admittedly limited knowledge of PR.
