In case you didn't notice, this statement came from the Office of the Press Secretary. I've stated numerous times, as recently as earlier today, that I believed the President would veto this.
I was wrong. I don't see how there will be a happy outcome to this based on today's statement. Bush's only card to play is a VETO. There wouldn't be enough votes to overturn that.
He signs, he loses - BIGTIME.
I too thought that as of yesterday but that isn't true. He can choose to announce he won't enforce the parts he believes are not constitutional.
