JMO....
North and South American Hispanics don’t relate to Cubans. They may all have similar roots from Spain/Portugal, but the cultures are not at all similar.
Cubans are generally either White or White/Black mix. The NA and SA Hispanics are generally White or White/Am. Indian mix.
Add-on to my post above...
I realize what I posted was somewhat simplistic and generalized. However, I truly believe there is a large cultural divide between NA/SA Hispanics and the Cubans and Puerto Ricans.
I’m a Natural Born Texan with ancestors who were here in the 1820s when it was still part of Mexico. Obviously, there are cultural differences between me and someone who has lived their whole life in one of the Northeastern States.
That’s essentially the comparison I was attempting to make about why “Hispanics” are not very supportive of Rubio.
