The Muhlenberg/Michigan poll released Wednesday found 60 percent of those polled believe natural gas companies have too much influence on Corbett's decisions on drilling regulation.
According to the poll, 84 percent of respondents say drilling companies should disclose the chemicals used in the hydraulic fracturing process used to tap the Marcellus Shale formation. But the poll says 41 percent of respondents felt the industry has benefited the state while 33 percent said it brought more problems than benefits.
The poll by the Muhlenberg Institute of Public Opinion and the Gerald R. Ford School of Public Policy at the University of Michigan surveyed 525 residents between October 6 and November 2. It has a margin of error of plus or minus 5.5 percentage points.
