As the presidential primary contenders campaign in New York, Sen. Bernie Sanders (I-Vt.) is hoping his position on hydraulic fracturing can help differentiate him from former Secretary of State Hillary Clinton.
In an ad and speech Monday, Sanders calls for an outright ban on hydraulic fracturing, or fracking, a process used to extract natural gas reserves from shale formations. Fracking uses a high-pressure stream of water, sand and chemicals to tap into shale formations. And there is a lot of natural gas contained in the Marcellus formation, which stretches up into New York state.
But the issue has been hotly contested in New York. Gov. Andrew Cuomo announced a ban on the process in December 2014 due to concerns about health and safety. The ban was finalized in June 2015.
