A plurality of registered voters support banning fracking, a new poll has found. Nearly 46% of respondents said they’d back restrictions to prohibit the controversial oil and gas drilling technique, according to a survey by the progressive pollster YouGov Blue. Of that figure, 32% said they “strongly” favored a ban. Meanwhile, just over 33% of voters polled opposed banning fracking, with slightly more than 22% saying they were “strongly” against the idea. Nearly 12% neither supported nor opposed a ban, and just over 9% said they were “not sure.” The partisan divide was more pronounced. Democrats supported the ban most, with 63% in favor, 19% against and another 19% unsure. Among independents, 44% supported a ban, 36% opposed it and 21% were undecided. Just 26% of Republicans backed a ban, while 24% were unsure and 50% opposed it.

The poll ― which Data for Progress shared with HuffPost on Wednesday ― was conducted last month among 1,380 voters, and findings for the entire sample group have a margin of error of plus or minus 3.1 percentage points. The survey prompted participants by listing the pros and cons of fracking. Noting that fracking fuels “one quarter of America’s energy production,” the question said fracking supporters “say it decreases electricity costs and reduces our dependence on foreign oil” while opponents “say that fracking pollutes local soil and water with known carcinogens and that we should invest in renewable energy instead.” The poll then asked: “Would you support or oppose banning the practice of fracking in the United States?” The findings come just before 10 Democratic presidential candidates are slated to take part in a seven-hour CNN marathon of televised town halls on the climate crisis.
