of course, any real bill would involve putting the sticks before the carrots. A 2 year period of employer/landlord sanctions, increased border security, fence construction, et al. if that is shown to be working, then we can talk about the carrots - guest workers, more green cards, etc.
my own hope - is that nothing happens. we have 2 national elections coming up in the next 2.5 years, let this be an issue that candidates debate on, and let the voters provide some consensus about what direction they want to go.
Unfortunately, it will probably be a completely stage-managed "debate", unless the voters really start raising hell over this. The two parties are in basic agreement on how to proceed, with only minor matters of detail separating them.
