Like, the old Cubans that really care about Castro are ardent Republicans. The younger ones are pretty on board with normalizing relations and probably don't care that a VP candidate said a couple nice things about literacy or healthcare. I don't see a demographic being lost here, besides there being a state party that has that sliver of people who really care.

It's like how 50% of Republicans want Medicare for All but 0% of GOP members of Congress support it. The political class is not the people at large, they often don't relate to each other at all.
