FYI...Puerto Ricans are US citizens. Therefore, if they are living in one of the 50 states they ARE living in their homeland.
Now, it appears your thread title is referencing the joke told at the Trump rally. My take is it was a joke...told be a professional comedian...offensive, tasteless and/or tacky jokes are very common for them. That said, if it was told at a campaign rally for me I would probably be ticked. I understand if it causes voters living there to vote for Commie-lahaha it isn't a big deal as PR has no electoral college votes. But I wouldn't like him pissing off voters in the places that do who are still undecided (all 12 of them).
