Ok, someone could take the pew research numbers on illegal immigration by metropolitan region, and then correlate that to Spanish radio listenership in those metros based on the Nielsen tlr data. As much fun as that is, and as much as I appreciate the HN readers demand such validation, I’ll let someone else run those numbers.
