I had not heard it either, it was buried in a long thread the other day.
Bush is obfuscating by stressing the supposedly rigrous requirements for citizenship, but not informing us that they get Green Cards on day one!
Being a citizen and a quarter will get you a cup of coffee and jury duty. A Green Card is the key that unlocks the treasure of being in the U.S.
Day one? Not the end of the line?
Document that.
