It is not by chance that Trump says that AGW is a hoax and that he supports coal subsidy. He KNOWS his base.
For the last F'n time, my comment was not partisan. Make that point to someone else it's got nothing to do with what I said.
As a counterpoint to your assertion, in the spirit of addressing what someone actually said, there is evidence to the contrary from recent polling.
Another recent Yale survey found that overall, 78% of registered American voters support taxing and/or regulating carbon pollution, including 67% of Republicans and 60% of conservative Republicans.
Of course polling is not perfect and people have to make choices when there are competing interests involved... but it points a less bleak picture than you do.
