With what little respect is due to the Huckster, isn't punishing a kid who moved in to Arkansas from, say, Wisconsin by charging them out of state tuition doing the same thing? After all, how was it their fault that their parents lived in Wisconsin?
I don't think Huckabee was advocating giving illegals who recently moved to Arkansas instate tuition. They had to meet the residency requirements. So assuming the requirements was 4 years. Then an illegal who moved to Arkansas 4 years before going to college would be eligible for in-state tuition, the same as a citizen who moved from Wisconsin 4 years before going to college.
If they hadn't lived in Arkansas for at least 4 years then neither the illegal nor the Wisconsin are eligible. If they don't meet the residency requirements than neither gets in-state tuition. That seems fair to me.
