Some of the party’s problems are hard and have no shortcuts. But the big one – figuring out whether replacing Biden would even help the Democrats’ electoral chances – is a good match for prediction markets. Set up markets to find the probability of Democrats winning they nominate Biden, vs. the probability of Democrats winning if they replace him with someone else.
(see my Prediction Market FAQ for why I think they are good for cases like these)
Before we go into specifics, the summary result: Replacing Biden with Harris is neutral to slightly positive; replacing Biden with Newsom or a generic Democrat increases their odds of winning by 10 – 15 percentage points. There are some potential technical objections to this claim, but they mostly suggest reasons why the markets might overestimate Biden’s chances rather than underestimate them.

My first personal encounter with the rarest book in American literature was memorable, even moving, for many reasons, but its physical appearance wasn’t one of them. If ever a book ought not to be judged by its cover, Edgar Allan Poe’s debut collection, Tamerlane and Other Poems, is that book. Known as the Black Tulip, only twelve copies appear to have survived since its publication in July 1827. That one of the last two in private hands is coming to auction this month, not quite two centuries later, marks an historic bibliophilic event.

Scientists now know that stress is intimately linked with many chronic diseases: It can drive immune changes and inflammation in the body that can worsen symptoms of conditions like asthma, heart disease, arthritis, lupus and inflammatory bowel disease. Meanwhile, many issues caused by stress — headaches, heartburn, blood pressure problems, mood changes — can also be symptoms of chronic illnesses.
Guillaume de Machaut, the master poet-composer of fourteenth-century France, served for many years as the canon of the great Gothic cathedral at Reims, where the kings of the realm were crowned. Machaut’s most famous creation, the Messe de Nostre Dame, has a singular place in musical history, because it is an early attempt at creating a comparably sublime edifice in sound—a six-movement work in four-part polyphony, lasting well over half an hour, in which austere, granitic harmony is set against delicate contrapuntal play and spiky rhythmic motion. This Mass is, in fact, the oldest extant piece of its type to have been attributed to a single composer. When, the other day, the San Francisco-based vocal ensemble Chanticleer sang it at Grace Cathedral, on Nob Hill, a suitable atmosphere of awe accumulated.
There are three tiers in the hierarchy of men’s professional tennis. The ATP Tour is the sport’s top division, the preserve of the top 100 male tennis players in the world. The Challenger Tour is populated mainly by players ranked between 100 and 300 in the world. Below that is the Futures tour, tennis’s vast netherworld of more than 2,000 true prospects and hopeless dreamers.

In the Jewish legend, the great warrior Samson ends up, as John Milton famously puts it, “eyeless in Gaza.” He is blinded by the Philistines and harnessed to a huge millstone, forced to drag himself around and around in circles, always moving but unable to go anywhere. Eventually, in the most spectacular of suicides, he gets his revenge by pulling down their temple on top of the Philistines, killing both them and himself. The story is apparently supposed to be heroic, but it feels more like a fable of vicious futility. Cruelty begets cruelty until there is nothing left but mutual destruction.
