Donna Martinez has a nice piece on immigration.
I don't know if she is right, though, about her claim that "real" conservatives should support immigration reform of the kind she outlines.
Her claim is logical, I think. But I don't know what a real conservative is any more. Numerically, most people who call themselves conservatives seem to advocate imposing their own religious views on everyone else, expanding government to accomplish that imposition, and spending lots of money on foreign adventures without any source of tax revenue to pay for it.
Still, a good read.
