I have been unfair to Republicans. Here I thought their knee-jerk resistance to immigration reform was based on nativist prejudices or a desire to pander to their basest base. Turns out, they were simply concerned for the well-being of immigrants. A front-page article in today's Times reports on the health risks faced by immigrants, who have inordinately high rates of heart disease, diabetes, and--I don't know, let's say rickets--especially when compared to their foreign-born relatives. I guess when people move to this country, the sudden availability of high-calorie, high-fat foods is too much to resist; or maybe immigrants just want to blend in with the girthy native population. Either way, it turns out those conservatives really are being compassionate.
