One of the issues at play here is the very real pushback from grassroots Democrats, but also a surprisingly large segment of Corporate America. When Exxon (!)  is calling Trump\s actions foolhardy, you know you've got a problem

The standard right wing talking points have to be discredited in the real world, and that's what is happening. Canada's Conservatives would be wise to pay attention.  For corporate America (and Canada) climate change action is a foregone conclusion already, it's really a question of whether the Right has figured it out - and increasingly it looks like they have.   Even Brad Wall, who is outspoken against carbon taxes,  leads a province with very aggressive renewables targets and that has put billions into carbon capture schemes.
