He has a bit of a Texas slur, as I noticed when I heard him speak Wednesday. Perhaps he said "to" rather than "through" and because of the different accent was misunderstood. Happens all the time in different regions of the country. "To" makes a lot more sense in the context of not being able to do his job.
Yeah, it could be a Bush-ism. Frankly, I'm not upset about the other verbiage. I hope God speaks through me in the things I do and say around people. Coming from someone like Clinton, such a comment would be the height of arrogance. Coming from Bush, it is an example of humble service to the Lord.
