A group opposed to Sen. David Vitter’s (R-LA) gubernatorial bid will begin running a TV ad on Thursday that includes a not-so-subtle reference to Vitter’s prostitution scandal.

The ad from the anti-Vitter Gumbo PAC closes with the camera panning to a crying baby wearing a diaper, noting that it “would be a crying shame for Louisiana” if Vitter were elected governor. One of the tantalizing yet unconfirmed sub-plots of Vitter’s prostitution scandal was a diaper fetish.

When asked about the significance of the diaper by TPM, the PAC’s director, Trey Ourso, said merely that they chose to use the baby because it would be a “crying shame” if Vitter is elected governor.

The ad also criticized the senator for voting to increase government spending and the debt, as well as for supporting Common Core.

The Gumbo PAC ad will run on Thursday night before and after the first gubernatorial forum, Ourso said. Vitter faces five other candidates in the debate. After Thursday night, Gumbo PAC plans on expanding its ad buy in the state, according to Ourso. He declined to provide the size of the ad buy.

Watch the ad below:
