I, too, favor immigration reform; but only if it is done properly.
The Simpson-Mazzoli disaster of 1986 should be quite instructive: If immigration reform does not contain border enforcement as a key component--in fact, if that does not precede legalization--we will end up with little more than amnesty, unaccompanied by anything that might prevent a future invasion of the southwest (mostly, by low-skilled workers).
Charles Krauthammer, I believe, has this about right: We should measure outputs, rather than mere inputs, when determining if border enforcement is working. More border agents, more miles of fence, and other guarantees are all well and good; but the only serious metric is how well these new measures are working: Has the flow of illegals slowed to a mere trickle, or does it remain a river?
Until that is answered--and answered correctly--there should be no legalization...
Real immigration reform to me is cutting off the benefits of violating our laws.
That is what we need.
