We describe a simple model of dark matter, which explains the PAMELA/ATIC excesses
while being consistent with all present constraints. The DAMA annual modulation signal can
also be explained for some values of the parameters. The model consists of a dark sector
containing a weakly coupled broken U (1) gauge symmetry, under which only the dark
matter state and the leptons are charged.
