Not long ago, a carbon tax was the untouchable third rail of climate politics.
“We have done extensive polling on carbon tax. It all sucks,” John Podesta, Hillary Clinton’s campaign chairman, wrote to another adviser in a memorable January 2015 email from the Wikileaks stash.

Ironically, the president’s rejection of climate science and his fossil fuel-focused agenda may have helped usher in an era when carbon taxation is politically thinkable.
