Who & why has a crush on Obama

You must have seen the music video I Got a Crush on Obama, but if you haven't (what a shame!) see it now:

Cool, isn't it? But honestly speaking what is it all about?

Are Obama Girl and Leah Kauffman fascinated with handsome democratic senator? Or maybe is that song an unofficial begining of Barack's presidential campaign? Or...

...or maybe somebody wants to discredit Barack Obama by connecting him with hot & sexy but not polite & moral Amber Lee Ettinger?

- So I put down my Kerry sign, knew I had to make you mine. Smart, black and sexy you're so fine, 'cause I got a crush on Obama - hottie sings...

Who does know the answer? Not me, you?
