Representing California's 52nd congressional district, Duncan Hunter was one of the most outspoken representatives regarding immigration reform and was the driving force behind the border fence.

It is to Hunter’s credit that he is strong on border control.
But true immigration reform must address legal immigration as well, and conservative reform of legal immigration means reducing legal immigration. Hunter may support that, but Tancredo actually sponsored legislation (that shamefully went nowhere in a GOP congress) to do it, and Thompson’s plan called for abolishing the Diversity Visa and ending chain migration. I’m not aware of any of the current crop of candidates calling for any of that. All of the top-tier candidates seem to be worthless when it comes to a conservative, comprehensive reform of immigration. And that is tragic since w/o it the GOP will be demographically buried in the next few decades.
