Abstract
The theory of topologically massive gravity in three spacetime dimensions, conjectured to be renormalizable by Deser and Yang, is analyzed using the recently-developed technique of nonlocal regularization. The validity of this technique, however, depends on the existence of a gauge-invariant measure for the nonlocal theory. Assuming that such a measure exists, we show that the possible obstacle to renormalizability found by Deser and Yang does not appear.
