While the Democratic candidates has thus far refrained from attacking each other, negative ads about Governor Corbett are fair game.

State Treasurer Rob McCord has made clear his strategy is to hammer Corbett as much as possible.

This isn’t the first time McCord and Corbett have gotten into a fight but the former’s latest commercial seems to indicate that there’ll be more to come.

“First, Rob McCord took on Tom Corbett’s plan to privatize the lottery and McCord won,” the narrator states. “Now he’s fighting Tom Corbett’s sweetheart deal for the natural gas industry.”

The spot goes on to tout McCord’s plan for a ten percent extraction tax on drilling in order to restore the Governor’s education cuts.

“If we’re looking for someone to take on Tom Corbett, Rob McCord is the only one who has,” the ad concludes.

The candidate initially tried to go the biographical route with his ads yet polling has indicated that his efforts weren’t as successful as they were for the front-runner Tom Wolf. This new advertising strategy appears to be an attempt to leverage the disgust that Democratic primary voters have for Corbett into support for McCord.

The other Democratic candidates for Governor are Congresswoman Allyson Schwartz and former DEP Secretary Katie McGinty.
