  The solution proposed by Zhao & Qin to the apparent conflict between
gravitational lens time delays, local estimates of the Hubble constant and
current expectations for the structure of CDM halos is discussed. Two essential
points emerge. First, the degeneracy is exactly the same as the local surface
density degeneracy previously discussed in the literature. Second, the proposed
mass distribution is inconsistent with CDM halo models. The Hubble constant is
raised by making the dark matter far less centrally concentrated than predicted
for CDM halos, much like the changes suggested for reconciling CDM halos with
the rotation curves of dwarf and LSB galaxies. Thus, while galaxies still have
dark matter, the Zhao & Qin solution to the time delay problem requires
fundamental changes in the CDM paradigm for halo structure.
