"Barack Obama is a Mac, and Hillary Clinton is a PC."

STYLES make fights — or so goes the boxing cliché. In 2008, they make presidential campaigns, too.

This is especially true for the two remaining Democrats, Hillary Clinton and Barack Obama. Reporters covering the candidates have already resorted to traditional analysis of style — fashion choices, manner of speaking, even the way they laugh. Yet, according to design experts, the candidates have left a clear blueprint of their personal style — perhaps even a window into their souls — through the Web sites they have created to raise money, recruit volunteers and generally meet-and-greet online.

On one thing, the experts seem to agree. The differences between hillaryclinton.com and barackobama.com can be summed up this way: Barack Obama is a Mac, and Hillary Clinton is a PC.
