The political class has finally begun to make sense of Majority Leader Eric Cantor's (R-Va.) out-of-nowhere primary defeat to economics professor David Brat. Two principal subjects have emerged: the Tea Party and Cantor himself.

In the narrative involving the former — Tea Party being shorthand here for very conservative voters — Cantor started off as a Tea Party spearhead who led a strategy of total opposition to President Obama that culminated victoriously in Republicans taking the House in 2010. Once Cantor was in power, however, he had to make the kind of decisions (like not defaulting on the country's debt) that failed to satisfy the base's unslakable thirst for total warfare. For versions of this story, see Dave Weigel at Slate and Brian Beutler at The New Republic.

The narrative that Republicans themselves prefer is that Cantor was a soulless ladder-climber who had completely lost touch with his constituents in Virginia's 7th District. They point to the fact that Sen. Lindsey Graham handily won his primary in South Carolina despite being one of the more moderate Republicans out there, and that Cantor tellingly spent Election Day at a Starbucks in D.C. hobnobbing with corporate lobbyists — not in his hometown. Republicans prefer this storyline because it is the one that gives them a prayer of uniting their excitable base with a more moderate platform that can actually win national elections.

So which one did Cantor in? The answer, most likely, is a bit of both. The problem for Republicans is that no figure at a national level has so far been able to thread this needle, and Cantor's demise is some pretty strong evidence that it may not even be possible. Ryu Spaeth

Late Wednesday, the Securities and Exchange Commission said that it discovered last month that a 2016 hack of its computer filing system for publicly traded companies "may have provided the basis for illicit gain through trading." The "software vulnerability in the test filing component of the commission's EDGAR system" has been patched, and while the "intrusion" was discovered last year, the SEC said, it only learned about the possible use of pilfered information to trade stocks for illegal profit after SEC Chairman Jay Clayton ordered a cybersecurity review in May 2017.

The SEC statement did not say why the agency didn't disclose the breach last year, when the system was hacked, or whether specific companies were targeted. The SEC is the federal government's main Wall Street regulator. "Cybersecurity is critical to the operations of our markets and the risks are significant and, in many cases, systemic," Clayton said. "We must be vigilant. We also must recognize — in both the public and private sectors, including the SEC — that there will be intrusions, and that a key component of cyber risk management is resilience and recovery."

Senate Republicans are planning to vote next week on the Graham-Cassidy health-care bill, and they can only lose two Republican senators to squeak it through with the vice president's tie-breaking vote. One of the Republicans who says he's a yes on Graham-Cassidy, Sen. Jeff Flake (Ariz.), came on Stephen Colbert's Late Show Wednesday night and explained his thinking. "Why not wait to know what you're voting on before you affect one-sixth of the American economy?" Colbert asked. "Let me say, I want a bipartisan solution," Flake replied. "Part of the problem with ObamaCare is that it was pushed through by one party, and we're going to have the same kind of problem if we just do this long-term," but right now, 200,000 Arizonans don't have viable insurance options.

Flake said he thinks health care is better managed at the state level, and that governors will do a better job than federal officials at enabling health care for less money. (The last GOP health-care bill in July was supported by just 6 percent of Arizona voters, according to one poll.) Colbert asked Flake if he thinks Republicans have the vote to pass it, and he said yes. "It's going to come down to the final few senators," he said. "I hope we can. Like I said, people in Arizona are hurting, and that's who I'm responding to. We've got to fix it in a bipartisan way going forward — obviously it is never good for one party to push something through on its own. In the meantime, we've got to make sure that everybody has insurance." Flake did not connect those two thoughts, exactly, but you can watch his full argument below. Peter Weber

Stephen Colbert's Late Show kicked off Wednesday night with an homage to the late horror director George A. Romero and the zombie genre he spawned, plus a dig at Zombie TrumpCare.

Yes, Republicans are trying once again to repeal and replace ObamaCare, Colbert said. "This is beyond beating a dead horse. This is getting damn close to beastiality." And they have until Sept. 30 to do it, minus three Jewish holidays, because that's when their filibuster-proof powers vanish for the fiscal year, and they've reserved next year for Democrat-free tax reform. "It's a race against the clock — they've got 10 days to overhaul the health-care system or everybody lives!" Colbert joked.

He explained how the bill works, roughtly, then noted that former President Barack Obama, who has gotten very gray — "That's how bad Donald Trump is," Colbert said. "Obama is aging faster watching someone else be president!" — weighed in on Wednesday, defending the law the colloquially bears his name. But Colbert used a quote from Trump adviser Stephen Moore about people only wanting insurance for their families, and a fake TV ad, to remind everyone what health insurance is actually about.

Colbert then found some bemused mirth in President Trump's invention on Wednesday of a new African country while meeting with African leaders. "Now, there is no such country as Nambia," Colbert said. "Despite that, they might soon have a better health-care system than we do." Peter Weber

An aid truck hired by the International Committee of the Red Cross to deliver aid to Rohingya Muslim refugees in Bangladesh drove off a road and into a ditch Thursday morning, killing at least nine aid workers and injuring 10 others. More than 420,000 Rohingya refugees have fled to Bangladesh from their home in Myanmar since Aug. 25, when an attack by Rohingya insurgents sparked a harsh crackdown on the minority group in majority-Buddhist Myanmar. The Bangladeshi workers killed and injured were delivering food packages to 500 Rohingya families, ICRC spokeswoman Misada Saif said, and the Red Cross and Red Crescent are "very shocked and sad" at the deaths of workers "there to help the people who desperately need help."

Hours earlier, a Buddhist mob in the capital of Myanmar's Rakhine state tried to block a shipment of bottled water, food, blankets, mosquito nets, and other supplies for the Rohingya being loaded onto a ship. Some 300 protesters started throwing rocks and Molotov cocktails at police trying to protect the loading of Red Cross supplies, and police fired in the air to ward them off, an officer tells The Associated Press.

Rep. Dana Rohrbacher (R-Calif.) believes the whole Russian election-meddling story is a farce, recently met with WikiLeaks' Julian Assange in London then reportedly tried to trade an Assange pardon for purported evidence exculpating Russia, and is so notably pro-Russia that his House GOP colleagues "joked" last year that he was probably on the take from Russian President Vladimir Putin. So, "who the hell is Dana Rohrabacher?" Seth Meyers asked on Wednesday's Late Night.

In his "check-in" on Rohrbacher, Meyers explained how "Putin's favorite congressman" came to admire the Russians, how he met and cavorted with Putin in the early '90s, and why Rohrbacher seems to turn up at meetings with many of the same Kremlin-linked figures tied to the Trump-Russia investigation. Oh, and he admitted to smoking marijuana. "So he's a weed-loving, pro-Russia guitar player," Meyers said. "He's basically the guy who ruined every party I went to in college."

Senate Republicans plan to vote next week on the Graham-Cassidy health-care bill, despite opposition from every major medical and patient health association, the insurance trade group AHIP, Blue Cross Blue Shield, every Democrat, Jimmy Kimmel, President Trump's ally Gov. Chris Christie (R-N.J.), and a handful of other Republican governors, and no Congressional Budget Office analysis of its affects on consumers and coverage. The legislation is believed to have the support of at least 48 Republican senators, with Sens. Susan Collins (Maine) and Rand Paul (Ky.) voicing opposition — though Paul also opposed earlier versions of similar bills and voted for them anyway — and Sens. John McCain (Ariz.) and Lisa Murkowski (Alaska) are noncommittal. It needs 50 votes to pass. With so much at stake, CNN dabbled in a little bit of body-language analysis from video of the Senate floor on Wednesday evening. You can watch below. Peter Weber

When President Trump announced that he would withdraw the U.S. from the Paris global climate agreement, there were only two other countries that had not signed on to the pact, designed to slow or reverse the effects of climate change: Syria and Nicaragua. On Wednesday, Nicaraguan President Daniel Ortega said his country will sign the agreement "soon." Nicaragua did not sign in 2015 on the grounds that it did not require deep enough emission cuts from wealthy nations, but Ortega said on state TV Wednesday that the country has decided to sign the accord now out of solidarity with "this large amount of countries that are the first victims, that are already victims, and that are going to continue suffering the affect of these disasters," namely countries in Africa, Asia, Latin America, and the Caribbean.
