If this were a Democratic Senator giving a speech in Spanish, I doubt there would be a single freeper defending him (or her, if it were Hillary). I know I wouldn't. This nation's language is English. People who insist on being hyphenated Americans don't help themselves or the rest of us. Martinez may have an R after his name, but that's not going to stop me from protesting this move toward the multilingual (and cultural) chaos that the Left is longing for.
It wouldn't bother me in the least and it wouldn't bother most freepers. Why should it? I would only mock it if the context demanded it, and if a dem did it, it probably would be laughable. But it would not be Spanish-speaking per se, but what and why they said whatever they did en Español.
