A plurality of registered voters support banning fracking, a new poll has found.

Nearly 46% of respondents said theyd 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.
