[EX Q]: San Diego (CNN) -- I bet it sounded like a good idea at the time. Now, not so much.

How did Perry get mixed up with that circus? Simple. The Texas governor got into a political scrape, and made the mistake of overcompensating. He was looking for quick validation from his party's nativist fringe because he had gotten hammered by GOP rivals for signing, in 2001, a reasonable bill in the Lone Star State that allows illegal immigrants who go to college to pay what other residents pay: in-state tuition.Ruben Navarrette Jr.: Rick Perry has hitched his wagon to Arizona Sheriff Joe ArpaioPerry was foolishly looking for quick validation from his party's nativist fringe, Navarrette saysJustice Department has accused Arpaio of discrimination and racial profiling, he saysA once-promising candidate has lost his bearings, Navarrette says of Perry
