University City state representative Maria Chappelle-Nadal is starring on radio ads paid for by the Gibbons campaign. 

The ads which appear to be in heavy rotation on FM 106.5 (The Arch) begin with Chappelle-Nadal mentioning her credentials as a national Democratic Party delegate, then she says, "even as a Democrat, I want to recommend Mike Gibbons..."  The spot then morphs into a negative ad on Koster hitting him on tax issues, state senate votes, and plea bargaining as a prosecutor.
