What is the group, Texans for Immigration Reform, doing to publicize all this? It sounds dumb, but you should send your story to an investigative journalist who has some teeth. Bill O can be silly and trite sometimes, but he has a HUGE issue with the borders. He may bite on this one if you send him a well-thought out email with actual proof of fraud.
The problem is that both political parties benefit from mass immigration.
The Democrats get votes, the Republicans get money from corporations who need cheap labor.
