Don't worry about it. The wild-eyed liberals wouldn't be caught dead moving to Texas. They would rather sit on their butts, collect public assistance, and complain about those corporate a**hats that laid them off, and post diatribes about Texas every time there is any misfortune (read the comments on any article about the explosion in West, or Hurricane Ike for examples).
The people that follow a company to Texas are the ones we want here. And, despite the unemployment rate, there are plenty of people here that would happily take the place of the ones that refused to move.
I like your optimism, and certainly hope you are correct.
My impression comes from meeting several transplants to my town from CA. They are all wild eyed liberals.
