Most do I would think with the exception of some at the top and the libertarian think tanks they fund. I've heard many of those claim that market failures don't exist when it's literally in every Econ 101 book. They make some good points that I agree with, but commonly make bad arguments (e.g. use the argument that it's ridiculous to regulate lemonade stands with health standards, so we shouldn't have health standards for meat packing plants and that sort of thing).
