The fact of the matter is the vast majority of people crossing the border are Mexicans. That's just the reality. And if they were something else, we'd be profiling something else. But they are what they are."
Romney:
http://www.politico.com/news/stories/0410/36432.html"Arizona's new immigration enforcement law is the direct result of Washington’s failure to secure the border and to protect the lives and liberties of our citizens,” Romney said.
“It is my hope that the law will be implemented with care and caution not to single out individuals based upon their ethnicity,” he added. “It is increasingly clear that the time has come for Washington to fulfill its responsibility for border security.”
