Some psychologist somewhere probably has written a paper about how the design and color choices a person uses on their web site reflects their personality.
But the site of just about every politician running for anything features the same friendly, patriotic, red, white and blue (lots of blue for some reason) motif with plenty of flag symbolism in sight.
So, what can then be said about John McCain? The site for his presidential “exploratory committee” is styled in shades of black and gray with a very industrial look. The only flag is hinted at in a faded watermark at the top of the page.
Just an observation about web design, not a political statement.
