I think maybe you should put down your pom-poms and come back to reality.
The GOP, like the RATS, is courting the hispanic vote, if for no other reason than because their numbers are expanding every year (Can anyone guess why?). That is the main reason why the borders were not sealed in the wake of 9-11 (or since) despite a tremendous hue and cry to do so.
Have you seen anything coming from Tom Delay that says he will indeed kill such legislation as Bush has asked for instead of just towing the party line?
Because otherwise it is just pure conjecture, which in this case only amounts to buying a bucket without a bottom to fetch some water.
