Shapiro ad seeks to boost Doug Mastriano in Pennsylvania gubernatorial contest

Democratic gubernatorial candidate Pennsylvania Attorney General Josh Shapiro recently launched a campaign advertisement designed to boost state Sen. Doug Mastriano, a Republican candidate some in the party worry may not fare well in the general election.

Mastriano is a front-runner in a crowded Republican gubernatorial field, although many voters remain undecided ahead of the state’s May 17 primary. In running the ad about Mastriano, Shapiro appears to agree with that assessment.
