I do not dismiss celebrity's endorsements.
No matter what people may think RM is very popular in PR.
I am sure you did not dismiss or ridicule when Oprah
came out for Obama. So I will not ridicule RM

However, even if Sen. Clinton got all the PR delegates it would not matter.
SD's are not worried how PR will vote in the Fall.
The biggest PR vote is from NYC (where they can by law vote)and they will vote Dem in the fall.
