Winter came and the city [Chicago] turned monochrome — black trees against gray sky above white earth. Night now fell in midafternoon, especially when the snowstorms rolled in, boundless prairie storms that set the sky close to the ground, the city lights reflected against the clouds

We hang on to our values, even if they seem at times tarnished and worn; even if, as a nation and in our own lives, we have betrayed them more often that we care to remember. What else is there to guide us? Those values are our inheritance, what makes us who we are as a people. And although we recognize that they are subject to challenge, can be poked and prodded and debunked and turned inside out bu intellectuals and cultural critics, they have proven to be both surprisingly durable and surprisingly constant across classes, and races, and faiths, and generations. We can make claims on their behalf, so long as we understand that our values must be tested against fact and experience, so long as we recall that they demand deeds and not just words.

On paper, at least, none of this would necessarily stop us from getting a stimulus bill passed. After all, Democrats enjoyed a seventy-seven-seat majority in the House and a seventeen-seat majority in the Senate. But even in the best of circumstances, trying to get the largest emergency spending bill in history through Congress in record time would be a little like getting a python to swallow a cow. I also had to contend with a bit of institutionalized procedural mischief — the Senate filibuster — which in the end would prove to be the most chronic political headache of my presidency. The filibuster isn’t mentioned anywhere in the Constitution. Instead, it came into being by happenstance: In 1805, Vice President Aaron Burr urged the Senate to eliminate the “motion to proceed” — a standard parliamentary provision that allows a simple majority of any legislature to end debate on a piece of business and call for a vote. (Burr, who seems never to have developed the habit of thinking things through, reportedly considered the rule a waste of time.) It didn’t take long for senators to figure out that without a formal way to end debate, any one of them could bring Senate business to a halt — and thereby extract all sorts of concessions from frustrated colleagues — simply by talking endlessly and refusing to surrender the floor. In 1917, the Senate curbed the practice by adopting “cloture,” allowing a vote of two-thirds of senators present to end a filibuster. For the next fifty years the filibuster was used only sparingly — most notably by southern Democrats attempting to block anti-lynching and fair-employment bills or other legislation that threatened to shake up Jim Crow. Gradually, though, the filibuster became more routinized and easier to maintain, making it a more potent weapon, a means for the minority party to get its way. The mere threat of a filibuster was often enough to derail a piece of legislation. By the 1990s, as battle lines between Republicans and Democra
