We can't expect Congress to do anything to improve the health care situation, as they would have to support something done by Democrats.Congress could easily rectify the uncertainty about what the statute says by passing legislation to alter the language, but has failed to do so. And the Republicans poised to take control of the full Congress next year remain focused on attempting to repeal Obamacare or otherwise damage it, not move bills to make it function better. States also could choose to set up exchanges to ensure their residents can receive subsidies, but none of the ones that have failed to do so are poised to change course.
Never mind that real people will lose health care as a result. The most important objective is to make the other party look bad.
