Polls show that the public is worried about climate change, but that doesn't mean that it is any more ready to bear any burden or pay any price to combat it.
If President Donald Trump claws his way to victory again in Pennsylvania and the Upper Midwest, his path will likely go through abortion and climate change, two issues on which the Democrats are most confident in their righteousness and willing to embrace radical policies that appeal to their own voters much more than anyone else.
Joe Biden, the relative moderate, is subject to these forces. He dumped his longtime support for the Hyde Amendment prohibiting federal funding of abortion last week and released a climate plan that, even if more modest than the "Green New Deal" (a low bar), is clearly derived from it.
