Didn't get to this yesterday, but the Washington Post had an editorial endorsing bilingual ballots. At the end, the Post's editorialists state that they "don't doubt that many more people will vote, and in an informed way, if they know what they're voting on." Yes, and everyone in this country has a way to make an informed vote. It's called learning English.
What's missing from the Post's editorial is the fact that few things divide a nation more than the lack of a common language. There's nothing wrong with citizen's knowing more than one tongue--I'm all for it. But all citizens should know one common language. Look at Canada (Quebec, specifically) for what can happen when a country has a large swath of citizens who cannot speak the same language as the majority.
