I have learned that "Obama girl" has been very popular in the USA by today's newspaper. This is interesting thing, I think. I tried to find "Hillary boy" or "Clinton boy" on the Internet, but I could not.
P.S. I can find the song's lyrics, here, thanks to Marian-san.
P.S. Thanks to joshf-san, I could learn about this song by "Hillary girl". I think it is very catchy and like it than Obama girl's. But I have not been satisfied with it yet because its singer is a girl, not a boy.
