A federal judge in Sacramento granted the Trump campaign’s request to block a California law that requires presidential candidates to disclose their tax returns to run in the state’s 2020 primaries. While the law applies to all presidential candidates, the judge said it was plainly targeted at one in particular. “The elephant in the room is President Trump’s tax returns — that’s what this is about,” he said. “But it does have implications that are far-reaching.” Politico | L.A.

In parts of the Sacramento–San Joaquin River Delta, the land has sunk 25 feet since the late 1800s. The phenomenon — known as subsidence — means aging dirt levees are doing more work than ever to keep water back. A breach could leave huge swaths of California without usable water for months, even years. “It’s Katrina on steroids,” a biometeorologist said. “We’re a $4 trillion economy. Think of shutting down water for 30 million Californians.” Bay Nature magazine

Homeless men in desperate circumstances had a nickname for the wealthy West Hollywood political activist accused of operating a drug den: “Dr. Kevorkian.” In a federal complaint, 10 men told investigators that Ed Buck, 65, paid them to use drugs and dress up in skimpy underwear.

As I lost the ability to walk, more people have followed in my footsteps.” N.Y. Times

If you’ve heard that homicides have been on the decline in Los Angeles, that’s true overall — but not for women. Since 2016, the number of female victims has been increasing. Last year, 114 women were killed in Los Angeles County, the most since 2010. In nearly half of the cases, the accused killers were former or current intimate partners. L.A. Times

Bon Appétit Magazine named the 10 best new restaurants in America. No. 1 is Konbi, a tiny sandwich shop in Los Angeles’s Echo Park neighborhood. The 10-seat space is an ode to Japan’s 24-hour convenience stores, and it makes a chocolate croissant, the magazine wrote, “worth planning your entire morning around.” Bon Appétit | L.A. Magazine

Before Bernie Sanders, there was Upton Sinclair. It was on this day in 1878 that the author, champion of the underdog, and socialist candidate for California governor was born.

Sinclair is best remembered for his 1906 book “The Jungle,” which exposed the grotesque conditions endured by both workers and livestock in Chicago’s meatpacking industry. It sold millions of copies, stirring the country. President Theodore Roosevelt called on the 27-year-old Sinclair to give him a firsthand account, culminating in a pure-food statute that led to the creation of the Food and Drug Administration.

Sinclair kept up pressure for reforms, annoying Roosevelt, who wrote a note to his publisher: “Tell Sinclair to go home and let me run the country for a while.”

But Sinclair, a mild-mannered man who stood 5’7″, was only getting started. In more than 90 books and thousands of speeches over the next six decades, he championed strong trade unions, birth control, an honest press, vegetarianism, education reform, and other causes.

Along the way he collected a Pulitzer Prize, fictionalized the Southern California oil boom in a book that inspired the film “There Will Be Blood,” and uttered his immortal aphorism: “It is difficult to get a man to understand something, when his salary depends upon his not understanding it.”

In 1923, Sinclair was arrested during a pro-labor rally in San Pedro after he began to read from the Bill of Rights. “We’ll have none of that Constitution stuff,” the arresting officer remarked.

During the Depression, Sinclair ran for governor as a Democrat under the End Poverty in California banner. Of the state’s 7 million inhabitants, a million were out of work. Sinclair appeared poised to handily beat the incumbent Republican Gov. Frank E. Merriam. But Hollywood and the state’s leading newspapers mounted an astonishing smear campaign.

“The prospect of a socialist governing the nation’s most volatile state sparked nothing less than a revolution in American politics,” wrote Greg Mitchell, author of “The Campaign of the Century.” Sinclair’s foes, Mitchell added, “virtually invented the modern media campaign.”

Sinclair lost. But his campaign changed the Democratic Party. Sinclairites were elected in Sacramento and Washington, where they fought for civil rights legislation and labor reforms. The California Supreme Court Justice Stanley Mosk later called Sinclair “the acorn from which evolved the tree of whatever liberalism we have in California.”

Toward the end of his life, Sinclair summed up his work this way: “The English Queen Mary, who failed to hold the French port of Calais, said that when she died the word ‘Calais’ would be found written on her heart. I don’t know whether anyone will care to examine my heart, but if they do they will find two words there — ‘Social Justice.’ For that is what I have believed in and fought for.” N.Y. Times | L.A.
