I suspect that you are a closet Ron Paul apologists, but let's play your game that the parody sucks.
So, tell me, why does it suck? Though it is subjective, surely you can back it up right?
Of course. A good song parody builds on its base song by using the base song's meter and melody to craft another song entirely. A bad song parody simply replaces existing words in the base song with new ones, Mad-Libs style---like you did.
Also, good parody songs are typically humorous. Yours isn't.
My criticism really stung you, didn't it? If you want to throw bombs with the big boys, you really should develop a thicker skin.
