Safer for who, the illegals?
That's the only gang of people they give a crap about.
Note the bios of the "American" governors:
California -- an Austrian
Arizona -- from New York, came to Arizona 20 years ago to be a Federal attorney. Spent most of her time in federal office pursuing any white Anglo-Saxon Protestant she could find to pursue, while ignoring the largest concentration of Al-Qaeda cells in the country. Undoubtedly the first lesbian elected governor of Arizona, or any state for that matter.
New Mexico -- Born in Pasadena, but raised in Mexico City from the time he was one year old. Mother was Mexican. That is the country he's loyal to.
Texas -- Well, almost an American. But then, Mr. Perry did sign the illegal alien tuition bill. As far as I'm concerned, Texas left the Union that day.
The governors of these states have no right to make any international pact. It says so explicitly in Article 12 of the United States Constitution. A lot of them alleged in the fight over 187 that "a state can't make a law about immigration". It appears that they don't quite believe that now. Maybe that's because most of them aren't loyal to the United States, and have no idea what our Constitution says.
