No, it's not political, it's just a standings generated by Brad Sullivan, president of the Jack Graney Chapter of SABR for how teams fared in the standings from 2001-2008. The Yankees won the most games in the AL, while the Cardinals were kings of the NL. And between the two, the Yankees and Cardinals combined for one World Series championship in those eight seasons.
The closest "races" were in the Western divisions. The Athletics managed to withstand a 100-win season by the Angels to hold on to the top spot and the Dodgers stormed past the Giants this season to claim the NL West title.
The Blue Jays missed finishing at .500 for the 8-year period by one game. The Blue Jays had a game against the Devil Rays cancelled in 2004. The Brewers finished 1/2 game better than the Reds because of a 2004 cancellation against the Pirates.
Colorado managed to make it to the World Series once during this time period despite finishing with more losses than any other team in the NL West.
Florida was the only team to win a World Series during the Bush 43 years despite having an overall losing record.
Tampa Bay's 97-win season this year brought their eight year winning percentage up to a whopping .419.
