Apparently this ties into one of the ballot questions which concerns English immersion. This ballot referendum proposes to do away with Spanish taught classes in public schools and force students to learn English. Romney is for it and O'Brien is against it.
The Democrat/Socialists want to keep Hispanics speaking Spanish so that they are at a perpetual disadvantage (and thus need a "helping hand" from the gub'mint). The Republicans want to force students to learn English so that they can become productive and happy members of our society.
