A great deal of noise is made about how illegal immigrants are "illegal" and that should settle the issue. Proponents of this issue as one that matters continue to say that this is also a security issue, although they never offer a single statistic to substantiate this claim as any thing other than speculation.
To illustrate the absurdity of this, imagine taking an issue that also cracks down on "illegal" behavior and actually has statistics to show that it is a national security issue - something that kills about 20,000 Americans a year. Imagine trying to win an election on the basis of "cracking down" on speeding.
Illegal immigration as a political issue is not about legality or about security. It is about xenophobia, which I am pretty sure is Greek for fear of Hispanics.
