Presidential Ties/Colors

Is it me or does anyone else wonder why every time we see President Bush, even while rhe was running for office in 1999, that he always wore and still wears the same color tie? You know the one…the light blue color. Who is the brain power behind this decision? Now, every once and awhile he will bring out the red tie, but that does not seem aspopular as the light blue color. Is wearing the same color tie supposed to help us recognize the President? Seriously, I would like to know the reasoning behind this. I have never purchased a tie, but I am aware that there are a great many colored/patterned ties out there. So seriously…what is the deal?
