  Yang-Mills theory in four dimensions formally admits an exact Chern-Simons
wavefunction. It is an eigenfunction of the quantum Hamiltonian with zero
energy. It is known to be unphysical for a variety of reasons, but it is still
interesting to understand what it describes. We show that in expanding around
this state, positive helicity gauge bosons have positive energy and negative
helicity ones have negative energy. Some of the negative energy states would
have negative norm. We also show that the Chern-Simons state is the
supersymmetric partner of the naive fermion vacuum in which one does not fill
the fermi sea. Finally, we give a sort of explanation of ``why'' this state
exists. Similar properties can be expected for the analogous Kodama
wavefunction of gravity.
