SAN DIEGO — If Americans want to fix the immigration system, the first thing they need to do is cut through the fog of lies, contradictions and partisan spin that make it hard to see what is really going on. Then they’ll understand who is really to blame for the fact that we don’t have comprehensive immigration reform and the adjoining fact that a record number of illegal immigrants, nearly 2 million, have been deported and thousands of families divided in the last five years. The Framers divided the government into three branches, and gave the executive branch the power to enforce the law, including immigration law.
