This is a huge issue right now. All candidates should be thinking about it and studying it.
I live within 10 miles of the US/Mexican border. So I, of all people, realize what a critical issue it is. Candidates can and should address the issue but talk of sending troops will not help one get elected. So in that sense I am happy to see Perry with foot once again firmly planted in mouth. But the reality of our actually sending troops is scant so he was just blowing smoke — expensive smoke as I believe this will hurt him when he tries explaining it at the next debate.
