Here I think he has a point, and here conservatives can find common ground with him:
"Paul, R-Texas, strongly opposes granting "amnesty" to the estimated 12 million illegal immigrants in the United States today. So I asked him what he'd do with all those immigrants. Would he try to arrest all of them? "I don't think anybody could find 'em. I don't think anybody knows where they are," he said. "But if they come for welfare benefits, and you know they're illegal, deny them the benefits." That's the crux of Paul's approach: deny the immigrants the welfare and social services that many of them now receive. "Get rid of the subsidies," he said. "You subsidize illegal immigration, you get more of it."
