Yeah, that was pretty much a given. Whether or not I agree with his cabinet choices—and I'm feeling a lot better about them these days after the Chu choice—his story was inarguably the most important single person's story of 2008.
Yes, the crash was probably a more important story, but then again, the crash also proved decisive in washing away any remaining fears about Obama's "communism". After all, if capitalism has failed so badly that Tom Friedman is starting to draw comparisons between Communist China and America where China comes off looking better, screaming about "pinkos" just isn't going to get much traction.
Obama rose from an also-ran candidate as of this time last year to the President-Elect of the United States of America, and did it by understanding its electoral machinery and national mood more completely than any candidate in living memory. One can only hope that he'll keep it up.
