The discrepancy between dynamical mass measures of objects such as galaxies and the observed distribution of luminous matter in the universe is typically explained by invoking an unseen ``dark matter'' component. Dark matter must necessarily be non-baryonic. We introduce a simple hypothesis to do away with the necessity for dark matter by introducing an additional non-gravitational force coupled to baryon number as a charge. We compare this hypothesis to Milgrom's Modified Newtonian Dynamics. The model ultimately fails when confronted with observation, but it fails in an interesting way.
