There is power in fantasy, especially in stories that urge us to face the impossible or find ways to survive. And sometimes if we wait long enough, what is imagined on the page or the screen comes true. Before our nation elected President Obama twice, science fiction writers like Philip K. Dick and Irving Wallace penned novels that featured black presidents. Comedians like Bill Cosby, Richard Pryor , Paul Mooney and Eddie Murphy took on the role satirically, and the actors James Earl Jones, Morgan Freeman and Dennis Haysbert all acted as president in television and film. What looked like fantasy decades before was made more possible because we imagined it.
