I pointed this out a week or two ago.
Cubans are historically Republican for much the same reason that the South was Democratic for 100 years following the Civil War. Cubans blamed Kennedy, thus Democrats for the failed Bay of Pigs invasion...just as the South blamed Lincoln, thus Republicans for the Civil War.
Hispanics have been historically aligned with the Democratic party.
The only thing Cubans and other Hispanics have in common are language. They are ethnically and culturally different people.
That may be part of it Fuzz. But I'm talking why the Latino will not vote for Rubio. The process of getting into this country legally is different for Cubans than it is for any other Latino community. That resentment is strong with Latinos toward Cubans as Cubans will feel more privileged than other Latino communities because they get amnesty as soon as they step on American soil whereas that isn't the same for other Latino communities. . There is an air of snootiness that rubs the Latino community in the wrong way.
So Republicans cannot and should not depend on Mark Rubio for bringing them the Latino vote. It will not happen.
