Yes, he's Honduran. And if you think that a Mexican or a Puerto Rican or a Cuban-American all think that he and they are the same ethnic group, you're mistaken.
Mexicans, Puerto Ricans, Hondurans and Cubans are like Jamaicans, Canadians, Autralians and Yanks. You can gather the latter under the umbrella of "The English-Speaking World" but, beyond a very broad category such as that, they certainly don't consider themselves as part of the same ethnic group.
I must admit that I had never noticed that New Jersey Democrat Congressman Bob Menendez was of Cuban ethnicity. Since Menendez likes to play such games, I guess the rest of us Cuban Americans will have to claim that he is not "a real Cuban American".
Cuban American equivalents for the Southern term "scalawag" would be "infiltrado", "Comunista" and "Fidelista". So, Menendez is not "a real Cuban American" as he is simply a "Comunista infiltrado". There. I feel much better now.
But "real" or not, if Menendez were ever nominated for any high Court position, I would bitterly oppose him.
I would not care if he were "Latino", Hispanic", "Cuban American", my first cousin or my brother. I would oppose him because of his politics. Everything else is demogougic window dressing.
When it comes to politics, I don't vote color, religion, gender or ethnicity. I vote for who can best serve America.
