Interesting twist on the darkness theme. Looking into the cup of black coffee is like looking into the darkness of and overworked life that just repeats itself over and over every day. It is a certainty that many voters will NOT see the darkness in this image. The simplicity and perspective of this image is it's strength.
That cup helps dispell my morning darkness! Like the photo, and it's graininess. Works for me...it evokes that out-of-the darkness feeling when I wake up.
