Helllllooooo! Please read what you just wrote. Then really think about what will be necessary to administrate President Bush's proposal. More importantly, Bush's proposal, to actually work, presumes that we gain effective control of the border. If he can presume that that will be achieved in the future, he should implement it now as a show of good faith.
Bush's proposal, as presently formulated, is election year, pie-in-the-sky nonsense. Think about "anchor babies". Think about the media's presentation of stories about guest workers and their families being escorted out of the country after 6 years. Just how long would politicians hold up that end of the bargain under that kind of pressure? In practice Bush's plan would be a disaster for this nation.
