Watchdog groups say the natural gas industry is pumping hundreds of thousands of dollars into Pennsylvania's gubernatorial race and most of it is going to Republican nominee Tom Corbett.
Conservation Voters of Pennsylvania and Pennsylvania Common Cause released a report Thursday on campaign spending totals through Sept. 13.
Corbett, the state attorney general, opposes a new tax on natural-gas drilling on the Marcellus Shale reserve. Democratic hopeful Dan Onorato favors such a tax to raise money for environmental protection.
The groups say Corbett's campaign received $334,500 from natural-gas industry political committees and executives during the 97 days covered by the latest campaign finance reports. They say that works out to nearly $3,500 a day.
Onorato received $45,000 during that period -- an average of less than $500 a day.
