I think it has something to do with the convention. There was a thread about his strategy that was on here months ago and it mentioned getting the delegates from Guam as part of it, and it had to do with convention delegates to get the nomination.
Currently, you have to win at least 8 primaries/caucuses to have your name placed in nomination at the convention. That includes places like Guam, Puerto Rico, American Samoa, the Marianas, etc. Those are all places that a lot of the candidates ignore, but if Ted can pick up those, he can get 5 or 6 wins fairly easily.

not many but its always interesting to see whom Guam, American Samoa, Puerto Rico, USVI, and DC vote for ...
usually the most liberal of the candidates but sometimes not...
