They are just song lyrics from a song off of a so so album. American Idiot is somewhat of a political album, Bush was an easy President to write about. And lots of artists did Green Day is nothing special. Not all lyrics have meaning or at least a meaning that is meant for the listeners. Green Day has been compared to the likes of the Ramones and Rancid. I throw my head back and laugh, they wish they could be half as good. Without bands like them they would not be here. In interviews the members of Green Day even say it. Green Day is a couple of notches below the upper echelon of punk music. The fact that they are a blend of pop punk makes them so. Its not inherently bad its just not pure punk. Green Day to me has always been one of those bands that always seems to be second fiddle to everyone else. Even after all these years they can never seem to shake that label. But they wear it like a badge of honor, and it has not slowed them down. Green Day just will never get over that hill.
