I can help with this.
Obama joins the LA punk scene and starts his own band. "Darkest Africa" gains some mainstream notoriety after their accidental and fluke hit song, a collaboration between the former members of British Goth Rock band Bauhaus (Performing as "Love and Rockets") and Darkest Africa sends Barry Dunham's band into the top 5. Love and Rockets' career takes off, spawning a few hits in the early 90s. Love and Rockets reforms as the Bauhaus, Darkest Africa then breaks up.
In 1995, after the breakup of Nirvana, Dave Ghohl is looking for a new band to play with. Ghrol wants to have 2 lead vocals in his new band, as a way to break from the traditional pattern of having one lead singer. He auditions many other singers, including Perry Ferrel, Layne Staley and Lajon Witherspoon. He eventually settles on former frontman for Darkest Africa, Barry Dunham. The Foo Fighters, with its crooning, soul filled lead singer, transcend many genres of music, from Folk Kenyan to Hawaiian to Soul to Punk to Grunge and influences a wide group of musicians.
John Edwards/Carol Mosley Braun goes on to win the DNC nomination in 2008, but loses to the politically astute John McCain and his running mate JC Watts in the general elections.
Dunham then gets a lot of negative press after calling VP Elect Watts a "house negro", and is pressured to apologize on foofighters.com for his comment.
