Hard Numbers: The Packed Democratic Presidential Calendar

30 million: When police arrived at the home of Peru's former President Alan Garcia on Wednesday to arrest him on bribery charges, he killed himself. Brazilian construction firm Odebrecht, focal point of the enormous, multi-country Lava Jato corruption investigation, has admitted to paying $30 million of bribes in Peru since 2004. All of Peru's living ex-presidents are either in jail or under investigation for corruption.

20 billion: The EU this week threatened tariffs on $20 billion of US goods ranging from ornamental fish to exercise equipment as part of a long-running dispute over aerospace subsidies at the World Trade Organization. Washington recently listed $11 billion of European items that could be subject to new levies. Upcoming US-EU trade talks should be fun.

1,800: China granted permanent residency to just 1,800 foreigners in 2017, the latest year for which data is available, compared to about 1 million "green cards" given by the US to immigrants each year. Relative to its size, China is home to fewer foreigners than almost any other country in the world.

64: It may not take long for Democrats to find their 2020 presidential nominee. Under the current schedule, 64 percent of pledged delegates to the Democratic Party's national convention will be awarded in the first seven weeks of primary elections and caucuses, from February 3 to March 17, 2020. That percentage will increase if Colorado, Georgia, and New York—three large states that have not yet set a date for their votes—land during that period.

Why didn't Uber's IPO perform as promised?

Because they're losing tons of money. Because Lyft didn't do that well. Because their expansion into international markets, where they planned to go, has been harder than expected. Tough times at Uber.

Will cutting Huawei off from American technology hurt?

Trick question! Will it hurt Huawei? Yes, definitely. Will it hurt the American companiesthat supply Huawei? Yes definitely. Will it hurt consumers everywhere? Probably. Unless it changes the dynamics of the U.S. - China trade relationship in such a way that helps everybody, which is possible.

Should more cities ban facial recognition technology?

There's a tradeoff between privacy and safety. San Francisco just blocked facial recognition technology to help privacy but I think most cities are going to care more about their police departments being maximally effective and will choose safety.

In recent years, the accelerating cross-border flow of migrants fleeing violence and poverty has remade the politics of Europe and the United States. A startling new study from Stanford University warns that the conflicts we've seen to date may just be the opening act of a much larger and more dangerous drama.

Here's the study's argument in brief:

President Donald Trump again dramatically escalated the stakes in the US-China rivalry on Wednesday with a move that made headlines in the US while landing like a grenade in Beijing.

The US Commerce Department announced yesterday that Huawei, China's leading tech company and already the source of major controversy, has been added to a list that prevents US tech suppliers from selling to Huawei without a license. That's even more important than the executive order, also published yesterday, that bans US telecom companies from using Huawei equipment.

Voters in Australia head to the polls tomorrow to elect a new government. Though few outsiders closely follow politics in this country, this election tells interesting stories about three of the most important issues in today's world: Immigration, climate change, and managing changing relations with China.
