"...even if Obamacare were as bad as tea-party types say it is (see Lexington), it would still be reckless to use the debt ceiling as a bargaining chip to repeal it, as some Republicans suggest.

What can be done? In the short term, House Republicans need to get their priorities straight. They should pass a clean budget resolution without trying to refight old battles over Obamacare. They should also vote to raise the debt ceiling (or better yet, abolish it). If Obamacare really does turn out to be a flop and Republicans win the presidency and the Senate in 2016, they can repeal it through the normal legislative process.

In the longer term, America needs to tackle polarisation. The problem is especially acute in the House, because many states let politicians draw their own electoral maps. Unsurprisingly, they tend to draw ultra-safe districts for themselves. This means that a typical congressman has no fear of losing a general election but is terrified of a primary challenge. Many therefore pander to extremists on their own side rather than forging sensible centrist deals with the other. This is no way to run a country. Electoral reforms, such as letting independent commissions draw district boundaries, would not suddenly make America governable, but they would help. It is time for less cliff-hanging, and more common sense."
