Well I've read the whole article from the beginning and it is what Bush wants, he's wanted to amnesty all illegal aliens since he got into office. He's now under the belief he can twist Congress's arm and get whatever he wants, and the passage of CFR and the Medicare bills provide enough reason for him to think that.
He will pressure Congress to go along with this lunacy, and while you may be right they will not, then again they may unless we the voters speak loud and clear: "read my lips, no new amnesties."
