Do they? Or do they want to reduce some of the more obscure, less clearly useful regulations?
Have you heard any advocacy for say, removing catalytic converters from cars?
The most common thing I've heard is states rights, and not having this be a Federal thing, which isn't really about pollution.
Yes. Spend time around car culture and you’ll see there are tons of people who advocate for the removal of catalytic converters and a drastic reduction in emission (and safety) standards. There are people proud to roll coal.
Also “states’ rights” arguments are almost always code for something else. The SR argument is never about the finer points of federalism.
Trump did run pandering to conservative wishes to defund the EPA. Trump won and is defunding the EPA. So yes.

So obscure they involve the primary budget for the office and the main regulations enacted by them during Obama's time.
