The narrative of the 2020 Democratic primary shifted following a strong performance by Sen. Kamala Harris (D-Calif.) in the first debate in June. But two months later, a new poll puts us roughly back where we started.

While Harris experienced a major polling bump following her break-out first debate, during which she confronted former Vice President Joe Biden on busing, she's been slipping ever since the second debate in July. In the latest poll from CNN and SSRS released on Tuesday, she's down to 5 percent support, a 12-point drop from a post-debate June poll that had her at 17 percent support.

This poll brings Harris down to 10 points behind Sen. Bernie Sanders (I-Vt.) and 9 points behind Sen. Elizabeth Warren (D-Mass.), as well as 24 points behind Biden; she had been just five points away from the former vice president in June. CNN notes that this 5 percent support for Harris is about where she was before the first presidential debate.

Biden went up seven points in the CNN/SSRS poll compared to the one conducted in June, putting him at 29 percentage points, 14 points ahead of his closest rival, Sanders.

After a performance in the second Democratic debate that clearly did not make as much of an impression on voters as her first, Harris will next have a chance during the third debate in September, which will now have at least 10 candidates. With this CNN poll, former Secretary of Housing and Urban Development Julián Castro has met the qualification requirements. Should just one more candidate qualify, the debate will be split into two nights again, meaning Harris may or may not get another rematch with Biden.

CNN's poll was conducted by speaking to 1,001 adults nationally over the phone from Aug. 15-18. The margin of error is 6.1 percentage points. Read the full results at CNN. Brendan Morrow

Is there still a chance that Spider-Man could swing back home into the Marvel Cinematic Universe? Potentially, although it's not looking good.

Reports emerged on Tuesday that Disney and Sony failed to reach an agreement that would allow them to continue sharing ownership of the Spider-Man character, with Marvel Studios President Kevin Feige no longer set to be involved in the upcoming sequels starring Tom Holland.

This would likely mean that Spider-Man would exit the Marvel Cinematic Universe completely, no longer being able to interact with any of the Avengers in future films. Considering Spider-Man was just recently set up as a crucial component to the rest of the Marvel franchise, and effectively the next Iron Man, this would be a radical shift.

Sony in a statement now says that "we are disappointed but respect Disney's decision." The point of contention, according to Deadline's Tuesday report, was Disney wanting a 50-50 co-financing arrangement on future Spider-Man films. This was reportedly far too high for Sony, which made counteroffers that Disney turned down. The current deal sees Marvel get five percent of the first-dollar gross.

In its response, though, Sony suggests the issue is actually that Feige does not have "time" to work on a movie series not owned by Disney due to his "many new responsibilities," but Deadline writes that this "seems like spin."

Sony also says that "we hope this might change in the future," leaving the door open for a deal to still happen. Indeed, Variety cites a source as saying a deal remains possible, although talks are not currently ongoing. But The Wrap reports that Disney "considers the matter closed," even as Sony believes that "negotiations are ongoing."

If director James Gunn can be re-hired nearly eight months after his public firing, anything's possible when it comes to Marvel. But should nothing change, don't expect Spider-Man to do whatever an Avenger can. Brendan Morrow

The heads of the National Institute of Drug Abuse (NIDA) and National Institutes of Health (NIH) correctly identified the nascent opioid abuse epidemic in March 2006 and nearly convinced then-Surgeon General Richard Carmona to issue an official call to action, the most potent tool the surgeon general has to alert the public, Politico reported Wednesday. But for reasons that aren't fully clear, "the effort didn't lead to any real action, and the toll of death and addiction climbed."

"Why it then didn’t happen is still a mystery to me," Geoffrey Laredo, a former senior NIDA adviser who worked closely on the call to action, tells Politico. "We were facing what we believed was a public health crisis that needed to be addressed and we had what we thought was an agreement with the surgeon general to do a thing. We produced that thing ... and then it never saw the light of day."

Carmona told Politico he held a number of meetings about the call to action with Health and Human Services Department officials and the George W. Bush White House Domestic Policy Council, but his office was dealing with other big crises, like obesity and bioterrorism. "The [opioid] crisis was in its infancy," he said. "It wasn't like we dropped the ball." His term ended a few months after NIDA Director Nora Volkow pressed him for urgent action, and when an acting surgeon general took over, "what little momentum had built for a public warning evaporated," Politico says.

"Had the call to action succeeded it would have been the first major attempt by the federal government to counteract the aggressive marketing of pharmaceutical companies that had led doctors to liberally — too liberally, in retrospect — prescribe the painkillers," Politico reports. Instead, "more than 133,000 people have died from prescription opioids since then — and hundreds of thousands more from street drugs including heroin and illicit fentanyl."

An Australian appellate court Wednesday upheld the 2018 conviction of Cardinal George Pell on charges of sexually molesting two 13-year-old boys in 1996 and 1997. The 2-to-1 verdict in Victoria's Court of Appeals sends Pell back to prison, where he is serving a six-year sentence. Pell's lawyer said the 78-year-old prelate will likely appeal the decision to Australia's High Court, though there's no guarantee the nation's final arbiter would agree to hear his appeal. Pell, the former Vatican finance minister and archbishop of Melbourne, is the senior-most Catholic prelate convicted of sexual abuse. He maintains that he is innocent.

Chief Justice Anne Ferguson said she and Justice Chris Maxwell "decided that it was open to the jury to be satisfied beyond reasonable doubt that Cardinal Pell was guilty," adding that dissenting Justice Mark Weinberg "could not exclude as a reasonable possibility that some of what the complainant said was concocted."

Advocates for sexual abuse victims cheered the verdict, the Australian Catholic Bishops' Conference said it respectfully accepted the verdict, and the Vatican, which is conducting its own investigation of Pell, confirmed "its closeness to the victims of sexual abuse and its commitment to pursue, through the competent ecclesiastical authorities, those members of the clergy who commit such abuse."

As soon as Wednesday, the Trump administration is expected to publish sweeping new rules for detaining minors who cross the U.S.-Mexico border, seeking to sidestep or terminate the Flores Settlement Agreement that has determined how the U.S. treats migrant children since 1997, ABC News and The New York Times report. The new rules, a version of which were proposed in September 2018 but never enacted, could allow the government to detain migrant children for longer than 20 days, revise the minimum standards of care children are afforded, and end some of all of the other protections set out in the Flores agreement. Once published, the rules will likely be challenged in court.

Administration officials told the Times that the new rules will maintain the underlying purpose of the Flores settlement and that all children will be "treated with dignity, respect, and special concern for their particular vulnerability as minors," as required under Flores. Migrant advocates disagree. "The proposed regulations do not implement the settlement," Peter Schey, who filed the original 1985 lawsuit with colleague Carlos Holguin, tells the Times. "They abrogate key terms of the settlement."

In the version of the rules proposed last year, the administration argued it can "terminate" Flores protections if it establishes its own replacement regulations. Trump and other Republicans say the Flores settlement encourages migrant parents to flee Central America with their children so they won't be locked up indefinitely. The Obama administration tried and failed to get out from under the Flores restrictions.

Schey and Holguin have returned to court again and again to enforce the settlement, and they've enlisted lawyers and law students to visit detention facilities, like the one in Clint, Texas. "It's like we are playing whack-a-mole," Holguin told the Times. "If someone had told me in 1985 that our work to protect children would continue into 2019," he added, "there is no way I would have believed it."

President Trump surprised, amused, and left lots of people aghast when he abruptly announced Tuesday evening that, because Denmark isn't willing to discuss selling Greenland, he is no longer visiting the country, its leaders, and its queen in the beginning of September. Maggie Haberman at The New York Times, for one, isn't buying Trump's stated reason for scrapping the visit — which, to be fair, is pretty unbelievable.

Haberman doesn't offer her own explanation. But in the wake of Trump's announcement, Twitter discovered a local Danish news report from last week: Coincidentally, former President Barack Obama is visiting Denmark again at the end of September. And some unkind wags drew their own conclusions.

It's clearly a coincidence that Trump called off his visit to Denmark a week after Obama's trip was announced — geopolitics isn't quite that petty. And yet...

Obama will speak and take questions from business leaders and students at Aalborg University in northern Denmark, The Local reports. Rich Henningsen, the moderator of the event, told local media that "President Obama is one of the people I look up to most in the in the world," while Aalborg's mayor, Thomas Kastrup-Larsen, gushed awkwardly: "I do not doubt for a moment that this will be a new climax for Aalborg and the whole of northern Jutland."

Meanwhile, a month before Trump's visit, thousands of people had "already signed up for a demonstration against him," the Copenhagen Post reported last week. "So it looks like the Danes prefer Obama over Trump after all. ..." Apropos of nothing. Peter Weber

Once they saw Monte, they knew they had met their leading man.

Animal trainers scouting for dogs to appear in Disney's live-action Lady and the Tramp came to the HALO Animal Rescue in Phoenix, hoping to find a few animals that would be a good fit. Monte, a two-year-old terrier mix, immediately stood out, as he's not only handsome, but he also knows how to sit, is good on a leash, and loves attention.

The stars of Lady and the Tramp are all former rescue dogs, and Monte will be voiced by actor Justin Theroux. All of the dogs have found loving families, Disney said. The movie will premiere on Nov. 12 on Disney's new streaming service. Catherine Garcia
