We report on our observations of the gamma-ray and optical photopolari- metric behavior of the radio-loud, narrow line type-1 Seyfert galaxy PMN J0948+0022 over a sixteen-month period. As this object has recently been sug- gested to represent a prototype of an emerging class of blazar-like objects, the observed properties are compared to those of blazars. While our observations do suggest a correlation between the gamma-ray and optical behavior, they do not offer conclusive proof that the emissive behavior of PMN J0948+0022 is due to a relativistic jet oriented close to our line of sight. We thus advocate for, and describe the requirements of, continued monitoring of this source in order to better address this issue.
