What the Crap is Going on in the US Virgin Islands?

I’ve always considered myself, in addition to being reasonable, to be intelligent. Simply put, though, I can’t figure out what is going on in the US Virgin Islands.

According to this link, the Republican caucus was held (Yes, the US apparently owns some kind of island or something somewhere. Yes, this territory apparently gets to vote on who the nominees will be. 9 delegates are at stake.)

Beyond that, I’m having a hard time making sense of anything. I think that the islanders vote for actual people who are will attend the convention in Cleveland as delegates. I also think that some of these delegates will be somehow bound by the vote on who to choose on the first ballot. After that, everything gets really hazy as all the articles assume you have knowledge that I don’t possess.

The results are in but all 6 delegates are unpledged? Huh? And what about the other three delegates?

If anyone can explain it to me, I’d appreciate it.
