Josh Shapiro raises $25.4 million in Pennsylvania governor's race, crushing Doug Mastriano

Josh Shapiro, the Democratic candidate for governor of Pennsylvania, crushed his Republican rival state Sen. Doug Mastriano in fundraising over the summer, raking in more than $25.4 million from June 7 to Sept. 19, according to campaign finance filings. By comparison, Mastriano raised nearly $3.2 million over the same three-month period.

Shapiro's massive cash haul brings the candidate's fundraising total this cycle to more than $50 million — the most of any gubernatorial candidate in the state ever. The fundraising totals come after the latest CBS News Battleground Tracker Poll released earlier this month showed Shapiro leading Mastriano by 11 points among likely voters, 55% to 44%.

Shapiro's fundraising has already outpaced the previous record set by former Gov. Ed Rendell, who raised $42.2 million during his 2002 campaign. More recently, Gov. Tom Wolf raised $32.8 million during his 2014 campaign, including $10 million in self-funding.
