There will be no phased implementation of any immigration reform. That's the word straight from the President (via Captain's Quarters).
It is nice to see politicians take principled stands the way President Bush has on this issue, as is the fact he has not turned to Rush Limbaugh, Sean Hannity or Laura Ingraham to provide him with the principles. He is his own person, and he is doing what he feels is right.
The fact that it is not what Hannity, Ingraham, Malkin, or others want is not a lack of principles, selling out, or betrayal as is claimed in this comment to Hedgehog. Quite frankly, those who do make such accusations are doing a very good impression of fanatics. If that is conservatism, count me out.
