One of the reasons I've been interested in the US health care is that here is something you can do, that could lift one of the largest burdens of worry from the shoulders of tens of millions of people for whom the rest of the economy isn't working. A lot of the things that are in Obamacare that Republicans don't like were deliberately put there to force Republicans to negotiate.
