Which we could, quite handily
it would not solve the labor vacuum that causes illegal immigration. Increasing legal immigration will do more to solve the problem than border security.
Fine, we can talk about doing that once we've secured the border, which wouldn't be hard to do at all. But legalizing illegals here without making them go back first is out of the question.
Actually I can talk about it now since I believe labor demand is the root cause of illegal immigration. When you guy win a Senate seat or Gov office we can talk about expelling 20 million people. Till then your just a Tancredo lackey and Tancredo's star is fading.
