1: The majority of illegal immigration in this country comes from the US/Mexico border. Not through Canada.
2: Illegal immigration encompasses far more than just Mexicans. It includes ALL races across ALL countries. The Mexican border is where the majority of them come through. Why not focus on the area where the majority comes from? When illegal aliens start to primarily come from Canada then we can focus on that. Until then we need to focus on where the majority is coming from. Which is the US/Mexico border.
