With a year and a half to go in the ’08 cycle, the idea of presidential candidates using the Internet is big news today, apparently. Eugene Robinson has a clever column today in the Washington Post, in which he compares the web sites of Clinton, Edwards, and Obama. I think he got it mostly right; his column is definitely worth the read. Over the course of the campaign, it will be interesting to see if these same attributes continue to define the web sites, or if strategies shift over time. A second question is whether these differences reflect substantive or tactical differences in the candidates or the campaigns at large. And, most important, whether these differences have any impact on who becomes president.
