Bush
In the days before the Sept. 11 terrorist attacks, immigration policy was going to be President Bush's signature issue. Five years later, Mr. Bush has at last realized some momentum on immigration policy, but it is probably not the activity he once anticipated. He has lost control of his own party on the issue, as many Republicans object to his call for a temporary guest-worker program, insisting instead that the focus be on shutting down the flow of illegal immigrants from Mexico.
