In spite of the "Hispanic" and "Latino" hype from the Left, there really isn't that much affinity between Cuban-Americans (who are typically middle class or affluent) and Mexicans (either Chicanos or Mexican immigrants), who are overwhelmingly poor. Until recently, Cuban-Americans were overwhelmingly Republican, while Chicanos vote Democratic. The only thing they have in common is their language.
Having said that, you're right in that the acceptability of a candidate to La Raza has more to do with the amnesty issue than anything else. Jeb Bush is basically an honorary "Hispanic" too.
“Until recently, Cuban-Americans were overwhelmingly Republican, while Chicanos vote Democratic. “
They’re not anymore? I thought they were the one smart Hispanic group and came here to actually be Americans, as opposed to just to take from us while retaining their own culture and having disdain for ours.
That would be sad if that too has changed.
