Democratic presidential candidates step on shaky political ground with fracking bans
DENVER — Several Democratic presidential candidates are running on a promise to ban fracking — and stepping on unstable political ground as they do so. An all-out prohibition on the controversial natural gas extraction process — backed by Sens. Kamala Harris, Bernie Sanders and Elizabeth Warren — has been well received by the liberal and climate-focused voters closely watching the primary. But the proposal also threatens to antagonize unions and voters in areas that depend on oil and gas for jobs.
