That is going to go down as his greatest achievement. Mike, there are liberal constitutional scholars - ones who supported the spirit of the intentions of the law - who believe that AHCA is going to implode over the next 2-3 years because of the way the laws were written.
There's a case pending in the U.S. Court of Appeals regarding subsidies, and others to follow. Just like badly architected bridges collapse, this will also ultimately crumble from the swift and careless way it was put together. It will crumble from the practical end as well as the design end. Whoever wins the 2016 presidential election will want nothing of it.
You're going to have to look long and hard to find legal scholars who will defend both the law and the way it's been carried out so far.
