  We examine whether the annual modulation found by the DAMA dark matter
experiment can be explained by Weakly Interacting Massive Particles (WIMPs), in
light of new null results from other experiments. CDMS II has already ruled out
most WIMP-nucleus spin-independent couplings as an explanation for DAMA data.
Hence we here focus on spin-dependent (axial vector; SD) couplings of WIMPs to
nuclei. We expand upon previous work by (i) considering the general case of
coupling to both protons and neutrons and (ii) incorporating bounds from all
existing experiments. We note the surprising fact that CMDS II places one of
the strongest bounds on the WIMP-neutron cross-section, and show that SD
WIMP-neutron scattering alone is excluded. We also show that SD WIMP-proton
scattering alone is allowed only for WIMP masses in the 5-13 GeV range. For the
general case of coupling to both protons and neutrons, we find that, for WIMP
masses above 13 GeV and below 5 GeV, there is no region of parameter space that
is compatible with DAMA and all other experiments. In the range (5-13) GeV, we
find acceptable regions of parameter space, including ones in which the
WIMP-neutron coupling is comparable to the WIMP-proton coupling.
