Janelle Monae released the album that had “Mr. President” on it in August 2008. Obama didn’t get elected president for another three months and didn’t take office until January 2009. While I give Ms. Monae credit for her visionary music, I think calling this song a protest song aimed at Obama is quite a stretch of the truth. https://itunes.apple.com/us/album/metropolis-the-chase-suite/id286635617
