Grover Norquist has been amazingly effective with his tax pledge that he has gotten almost all Republican Senators and Members of the House of Representatives to sign.
It turns out that he has thought a fair amount about immigration too. This is a very thoughtful interview from Reason TV. The interviewer is Matt Welch, editor-in-chief of Reason magazine. There's some interesting information in here about the history of immigration laws. In Grover's view, the guest worker program under Eisenhower was quite good. His discussion of this occurs at about the 10:30 point. His data are striking.
One little quibble: At about the 1:45 point, Grover incorrectly blames President Carter for the 55 mph national speed limit. The real villain was Richard Nixon.
