You reduce illegal immigration by making it harder to get jobs here, or easier to get jobs south of the border. This idea that we can’t pass an immigration law until we hit some imaginary security target is just a way to derail reform.

If immigration reform passes, it’ll be a big victory for sanity – nobody really believes it’s healthy for a country to have millions and millions of undocumented noncitizens living in the shadows. But it’ll also be a sign that the Republican Party has gotten tired of letting the Tea Party push it around.

Few people are as well-situated to speak about the laudable benefits of a humane immigration policy than me.
