Well .. I don't just think, I believe President Bush has submitted his life to GOD's direction. Of course he has to die daily, Jesus told us to pick up our cross and follow Him (daily).
"None are righteous" .. but then you write the scripture which opposes that statement and says, "so that in Him, we might become the righteousness of God". So .. if we're in Him, we are a partaker of that righteousness. We are no longer sinners. If we're still sinners then we didn't get saved.
We are saved through His finished work, not ours. Of course, we still sin (though, not as a habit of life) and deal with the effects of a fallen world, until we shed this tent and are glorified with Him. We wear His robe of righteousness (hence, partakers), not ours. It's all about Him.
But to answer your original question, yes, I think Bush looks to the LORD for his direction. Is he (Bush) perfect? Nah....and he would admit that.
