Although liberals and conservatives have their differences on such issues as human rights abuses and the rights of illegal immigrants, by and large I think it's incorrect to see immigration as a liberal/conservative issue. The fact is among those who favor the current immigration policies are many Republicans, including nonunion contractors, farmers, and immigrant populations themselves. Although immigrants vote Democratic, they don't vote that way by huge margins. So, among those Republicans who favor the current immigration policies are many Cubans and other Latinos, Asians, and Arabs. At the same time many labor unions want stricter policies because cheap illegal labor constitutes a threat to them. And among the states that are notorious for looking the other way with regard to illegal immigrants are conservative states like Texas, where righties would rather underpay an illegal immigrant than pay someone a working wage.
