I don't disagree with the level of importance -- it is small. But, seriously, it was very lightly distracting.
And I have ADD, not OCD, so if Bush had repeatedly changed his ties' pattern and color, maybe I would have liked it more. ;^)
And I'm not sure if that's good or bad for Bush....
I take it you've never made it through Bill Cosby's "Himself" video?
The skew on that tie would've made you seasick.
