As I recall, Perry said he didn't think the Arizona law would work well in Texas. They are working on a similar law for Texas in special session, but with changes to some of the specifics. That is one of the great things about federalism - it allows different states to try different solutions to social problems, solutions that are tailored to their specific situations.
I don't know enough about Perry to know if I would support him, but these kind of arguments don't carry much weight.
