It's true the popular vote can't be considered a landslide. However, the final tally of the electoral college was a landslide.
Either way, it was a convincing and thorough victory for Obama. The mooozie not only won, but he did so convincingly enough to have a strong mandate to govern. This is the unfortunate reality we must be prepared to deal with now.
In the final analysis, too many factors alligned against the McCain-Palin ticket to be overcome. The public's disdain for the incumbent Bush, the economic crisis, the media's one sided support for Osama, would have been very hard for even a very good candidate to overcome. One can debate whether McCain was a good candidate, but there's little doubt he ran a poor, badly strategized, uninspired campaign as well.
One can only hope Osama's honeymoon with the media and the American public is short lived. It's important to continue to work against Osama. We're in damage control mode now.
