I remember back when this guy was running his campaign. The fervor he inspired was down right scary. The blind fanaticism for reasons that no one seem to explain to beyond the idea of "It's historic" and "He's younger, and understands 'our' generation better." The simple fact of the matter is that "He's not Bush" is probably the correct answer. And while I hated Bush with a passion, the Bamster has managed to kindle a fire of Dantean proportions. The rage is still there but has been slowly subverted by disgust and depression.
Yes the song is supposed to refer to GW Bush. but I find it strangely fitting.
