Wasn't the Cuban girl identified as a Republican? I caught some of those episodes during one of the marathon broadcasts but only vaguely remember some of the news "press" that season generated.
I think that they were trying to create "controversey" by putting a Republican woman and a gay man in the same house. Now there seems to always be at least 1 gay cast member, with possibly some bi- cast members as well.
I didn't see the post you were replying to but I think you are talking about Rachel? (RW San Francisco, I think. With Puck?) She is (was?) a Republican and Catholic. Married now to another Real Worlder, with one daughter and another child on the way last I heard.
I don't know if Rachel is Cuban or not. Pedro was though.
