Simply put, rural US districts tend to be more conservative so tend to vote Republican. And the rejection of climate change theory has been a bedrock of Republican politics for years by now.
If one assumes
* that we are seeing early signs of persistent changes in weather pattern, then farmers, who professionally have been very attuned to long term weather conditions to be successful, ought to be aware of them.
Some examples of persistent weather patterns:
- California has had multiple years of drought.
- BC has had massive forest fires for 3 out of the last 4 years.
- Extremely deadly forest fires in Portugal and Greece.
- Global land and ocean temperature anomalies
- the Mountain Pine Beetle decimated pines in the BC Interior Plateau. This happened because we didn't enough -35C winter temperatures, which are the only real natural constraint to this pest.
Now, clearly, some of these can be attributed to modern forest management practices. But farmers are precisely the kind of people who analyze weather trends for a living. So I would expect at least some of them to be worrying about long term temperature and precipitation trends.
Has there been any grassroots movement among the US farming and ranching communities (specifically, on the Republican side of things), questioning the wisdom of continued rejection of the IPCC findings? Even if they retain conservative views on other issues such as crime, abortion and immigration.
* If you disagree with climate change or any signs of it happening at all, that's fine and you can put that as an answer. That's self-explanatory as to why farmers wouldn't worry then.
