Genuine bipartisanship assumes an honest process of give-and-take, and that the quality of the compromise is measured by how well it serves some agreed-upon goal, whether better schools or lower deficits. This in turn assumes that the majority will be constrained — by an exacting press corps and ultimately an informed electorate — to negotiate in good faith.

If these conditions do not hold — if nobody outside Washington is really paying attention to the substance of the bill, if the true costs … are buried in phony accounting and understated by a trillion dollars or so — the majority party can begin every negotiation by asking for 100% of what it wants, go on to concede 10%, and then accuse any member of the minority party who fails to support this ‘compromise’ of being ‘obstructionist.’
