Freedom caucus is the most backward conservative movement in the republican party led by rubio and most of the southern states including ryan.The oppose science, wish to sell monuments to highest bidder allow drilling on public lands. They want to sell public lands to developers allow for commercial enterprises at national monuments like grand canyon . They oppose OSHA unions,almost all regulations especially on banks and wall street & want to stop alot of research in medicine like stem cell and DNA modification because of the evangelical backing.I could go on and on but this gives you an idea.
