IMHO, enough light has been shed. The U.S. Government does not intend to do anything. The Ranchers need to proceed on their own, doing what is in their best interest, without attracting the attention of the media.
That's the botton line. If the government cannot or will not control the borders, it too will eventually become illegitimate. It's just not in their agenda, not part of their plan. It will be up to the people themselves, once they have enough and the crisis becomes more volatile. It will happen.
