We've already had tort reform. It didn't do anything. The ACA includes provisions to allow states to sell insurance across state lines. In fact, several states have tried it. Guess what? It didn't work, either. Exactly zero insurers lined up to try it. 

What in the world makes you think that excluding democrats from the AHCA will encourage them to sit down and work with the republicans? How in the hell do you get that idea?
