Not all Hispanics are seen as equal under the law (perhaps by some Anglos but not the Feds)
Miami Dade is home for just under 50% of all Cuban Americans, they are almost half of Miami Dade's population.
Cubans are not subject to the same immigration laws the rest of the Hispanic World faces. Once a Cuban's feet hit dry land they are 99% certain they will be American citizens and never will know the worry of a knock on the door decades later arresting them.
Cubans are roughly 4% of the estimated Hispanic population. 57% of the Cuban population is foreign born and they are US Citizens as mentioned above in a microwave fast process compared to ALL other immigrants attempting to gain Citizenship. Cubans are the most concentrated Hispanic group- 68% of all Cubans live in Florida. 63% of Cubans call themselves Cuban most often, 19% American.
Mexicans are the largest Non Cuban Hispanic group. 33% of them are foreign born. 57% call themselves Mexican, 23% American.
As many Hispanics would be happy to tell you (look at me) Cubans ain't like us- they have little, if any, understanding of what most immigrants from ALL other nations on this planet have to go through to be here. Rubio ain't like us- he has little, if any, empathy for those who live in the shadow world, who wait decades for citizenship (but gladly uses it to bash any pathway to citizenship for his 'fellow' Hispanics)
Jul 2015 he was for a Pathway, Sep 2015 he was 'firmly' against it. He ain't like us. Cubans ain't like us.
Until a non Cuban Hispanic city 'capitulates' I wouldn't get to 'concerned'....
