For 48 years—since one of my heroes, then-Governor Ronald Reagan, requested it-California has had a waiver from the federal government to clean our own air. If the President thinks he can win this fight, he’s out of his mind.

I am sick and tired of these fake conservatives who believe in states’ rights to make their own policies—as long as state policy is to pollute more. If you want to clean up your air, they throw federalism right out the window. I’ve had it with so-called pro-business conservatives who ignore what actual industry leaders say is best for business. The car companies’ own lobbyist said they hoped the administration would “find a solution that continues to increase fuel efficiency standards.” Let’s be clear: this is a stupid policy and no one asked for this. Businesses prefer certainty—not policies that change with the whims of each new White House.

I hope some conservatives with a conscience will act in Washington to defend California’s waiver based on these historic Republican values. But if not, I’d remind them that California has won this battle before. We will win again.
