Immigration War?

An upcoming American Civil War? Mark Lowry at American Chronicle seems to think so here. I see the idea as unfortunately possible in a generation or so unless real action is taken before then. History has shown that in nations divided by language, the minority group often wants to secede from the majority. In the last 50 years, Mexico's population has quadrupled from 25 million to over 100 million today, and during the same time the United States has been incredibly lax over border enforcement. Now, nearly every presidential candidate in the current race supports some kind of amnesty plan for illegal immigrants. They all seem to forget that the last one we did in 1986 only led to increased illegal border crossings. They also encourage horrific tragedies like the dozens of Haitians lost at sea today.
