part of a tribe that’s tribally opposed to clean vehicles.

Remember actions and words do not match here. Many of those people are happy to verbally say the support clean vehicles and such. However they are buying big trucks with big engines. They will vote for someone who says “get the oil company”, but if gas prices actually go up they will vote for someone else (and the people they vote for know it and so in turn say kill the oil companies, but when the oil companies want something the get it)
