But they're not undermining a carbon tax. They're supporting it, based on their understanding that American voters are extremely sensitive to gas prices, far beyond an extent that could be considered reasonable, and that for that and other reasons a carbon tax is politically unviable in the US. To be clear, I'm an extremely strong supporter of a carbon tax, to the point that I would vote for any politician who supports one regardless of their position on any other issues, and I would support the US creating ultimatums with other countries, including allies, to effectively force them to implement carbon taxes of their own. But I'm also open-eyed to the fact that the median American voter commutes something like 30 miles a day and has never taken an economics class.
