If it is delayed, look for GW to make an all-out effort to get amnesty passed during his last 2 years in office.
GW won't just let it go. He has been trying to get it passed since 2001, and he isn't about to stop now, nor during the next 2 years.
I don't think so.
He realizes he won't be able to get anything after this mid-term election, so he'll be content with the status-quo.
Before Bush put forth a proposal last year, the only push for "immigration reform" came from Glenn Spencer and his American Patrol and some fringe groups. It wasn't even in the top ten list of issues on the minds of American voters.
