Polling data on who is gonna win the election is definitively flawed.
This is not that and maybe she is working off flawed data there too, who knows, but I would suspect that the numbers aren’t particularly close if she is willing to shift positions in a way that will most likely get her labeled a flip flopper and similarly to the assault weapons ban, most workers non-union workers in the industry were probably already and continue supporting Trump.
So my assumption would be it’s better for her just to work off Joe Biden’s fracking policies than lean heavy on being anti-fracking.
I could be wrong. I honestly am not that worried about it from a political standpoint (super worried from a global warming water catching on fire standpoint). I think if she were to become president there would be less fracking and more environmental safe guards than if the Trump administration were in office.
