The Christian right was played like a violin by GWB .He is the same kind of "Christian" that most of our Presidents have been, cultural.
He has denied Christ with that statement, that does not bode well for him
I just had a though, maybe there is some truth to Bush's statement considering this:
John 4:21 Jesus said to her, “Woman, believe Me, the hour is coming when you will neither on this mountain, nor in Jerusalem, worship the Father. 22 You worship what you do not know; we know what we worship, for salvation is of the Jews.
He didn't say that she worships the wrong God, only that they worship a God that they don't know. Not knowing Him is the same as not being saved and results in going to hell, but it does leave wiggle room to say that they worship the same God.
