An NBC News/Wall Street Journal poll released Thursday shows former Vice President Joe Biden and Sen. Elizabeth Warren (D-Mass.) at the top of the 2020 Democratic field.

In the wake of the first Democratic debates, Biden has the backing of 26 percent of voters who say they will cast their ballots in the 2020 Democratic primaries or caucuses, while 19 percent support Warren. Sen. Bernie Sanders (I-Vt.) and Sen. Kamala Harris (D-Calif.) are tied at 13 percent and South Bend Mayor Pete Buttigieg follows with 7 percent.

Taking a closer look at the data, Biden outperforms the other candidates among older Democrats, African Americans, and Democrats who consider themselves moderate or conservative. Warren's strongest supporters are self-described liberals and people between the ages of 18 and 49. When asked about who would be their second choice for president, Harris came out on top with the support of 14 percent of voters, followed by Warren with 13 percent, Sanders with 12 percent, and Biden with 10 percent. Only 12 percent of all Democratic primary voters said they definitely know who they will vote for next year.

The poll of 800 registered voters was conducted July 7-9, with an overall margin of error of plus-minus 3.5 percentage points. Among the 500 Democratic primary voters polled, the margin of error is plus-minus 4.9 percentage points. Catherine Garcia

President Trump got no small amount of grief for suggesting Sunday that he would let Saudi Arabia decide what military action, if any, the "locked and loaded" U.S. should take against Iran if Tehran turns out to be behind an aerial attack on a major Saudi oil facility. But Trump's tweet has some strategic merit, argues Joshua Landis, director of the Center for Middle East studies at the University of Oklahoma. Here's the kernel of Landis' argument:

Congress, of course, has the explicit constitutional authority to declare war, and Saudi Arabia obviously does not. And Landis isn't arguing that Iran wasn't behind the attack — in fact, Iran has a clear motive — but he notes that the Saudis have been more cautions in assigning blame to Iran than the Trump administration has, and Trump was more cautious than Secretary of State Mike Pompeo. Trump also appears less than eager to get into another war in the Middle East — for good reason:

If Saudi Arabia is willing to gamble U.S. forces on an attack against Iran — calling Trump's bluff, in Landis' telling — Riyadh will foot the bill, Trump says. "The fact is that the Saudis are going to have a lot of involvement in this if we decide to do something," Trump said Monday. "They'll be very much involved, and that includes payment." Does that mean Trump has essentially turned the U.S. military into a Saudi mercenary force? Again, not necessarily, Landis says.

But you can't rule out the possibility. Peter Weber

Sean Spicer is clearly comfortable in green, whether that involves hiding in bushes or wearing a lime ruffled frock while making his Dancing with the Stars debut.

On Monday night, Spicer, the former White House press secretary, and his partner, Lindsay Arnold, danced the salsa to the Spice Girls' "Spice Up Your Life." Thankfully, the spice puns ended there, before Spicer was forced to eat a chili pepper or start throwing turmeric at the audience.

The dance lasted approximately one minute and 10 seconds, and although the judges only gave him a score of 12 out of 30, things actually went pretty well for Spicer — he didn't fall, he didn't drop his partner, he showed off his ability to point at things, he wasn't replaced by Melissa McCarthy halfway through, and he didn't claim his appearance drew the largest audience ever to witness a Dancing with the Stars premiere, period, both in person and around the globe.

The bond between pediatric nurse Claire Mills and her patient, Jackson, was instant.

Jackson was born five weeks early via emergency C-section, weighing just 3 pounds, 10 ounces. Mills, 25, works in the neonatal intensive care unit at a hospital in Texas, and she knew that Jackson's mother was struggling. Mills became a pediatric nurse because she was also a preemie, and she told Inside Edition she felt an "instant connection" with Jackson.

After several weeks, Jackson was discharged, and because it happened when Mills was off duty, she didn't have a chance to say goodbye. Mills called the social worker who had been assigned to work with Jackson's mom, and let her know that she was available to help the woman in any way possible. She soon heard back from Jackson's mom, who said she wouldn't be able to provide her son with the life he deserved, but Mills could.

Mills worried about raising him as a single mom, and talked to her own mother about it. Her mom encouraged her to follow her heart, and soon after, Mills started the adoption process. Jackson, now 4 months old, is all settled into his new home. He has gained weight and is in good health, and is "so happy," Mills said. Catherine Garcia

"Last week was the third Democratic debate, where 10 Democratic hopefuls went head-to-head — you know, I was actually going to make a joke about this story, but I don't think it needs a joke," Jimmy Fallon said on Monday's Tonight Show. "I think it needs to be slow-jammed." One of the 10 candidates at the debate, Sen. Kamala Harris (D-Calif.), also wanted to slow-jam the news. And so she did — the "news" here being her run for president, platform, and qualifications.

Harris had the relatively dry job of explaining her platform, with a few zingers thrown in; Fallon added the double entendres to spice it up a bit and some puns that might not exactly resonate with the all-college-audience — "last tango in Harris"? A Culture Club reference? — and Tariq Trotter, as per usual, had the best lines. If the other 20+ Democratic candidates want their turns to slow-jam the news, Fallon could easily keep this up until after the Iowa caucuses. Peter Weber

Over the weekend, The New York Times reported a new allegations of sexual misconduct against Supreme Court Justice Brett Kavanaugh from his college days, plus revelations about how the previously reported allegations were effectively ignored. "Every high school story or every college story we hear about Brett Kavanaugh just makes him seem worse and worse," Trevor Noah said on Monday's Daily Show. "And it's always something about him exposing himself."

"This story is messy," Noah said. "And what makes it messy is that the woman this allegedly happened to says she doesn't remember any of this happening. But the guy who says he saw it says that she was so drunk at the time he's not surprised that she can't remember it. And we may never know for sure what happened that night, especially since the FBI never even investigated it — which may seem a surprise to some people, but according to The New York Times, the FBI didn't look into a lot of the accusations against Kavanaugh."

"The FBI ignored 25 former Yale students who could have given evidence?" Noah said. "That's insane — because I didn't know the police also ignored white people. ... Now, in the FBI's defense, the reason they didn't interview these potential witnesses was because the White House reportedly told the FBI than when it came to Kavanaugh and the accusations, they were only allowed to interview 11 specific people and no one else. Which is not something you do when you're confident of someone's innocence."

"As has become normal in the age of Trump, reactions to this story have become as partisan as everything else is right now," Noah said, and there's no prize for guessing which side Trump landed on in the Kavanaugh imbroglio. "The Justice Department should come to his rescue? What? I feel like Trump doesn't really understand how the government works." Watch below for some safe-for-work theories on Kavanaugh's alleged proclivity for exposing himself at parties. Peter Weber

Fox Business host Lou Dobbs, an enthusiastic supporter of President Trump, went a little over the top last week after a visit to the White House. The Daily Show didn't have to do much to point out how, um, uncomfortably effusive Dobbs was in his praise for Trump, just superimpose his face onto state TV in cult-of-personality North Korea.

The optimistic ranking of Trump's presidency is what it is — fanboys are gonna gush. And to be fair, when Dobbs claims "there's sunshine beaming throughout the place, and on almost every face," he's talking about the White House in early September. But either every tell-all account of life in the Trump White House is wrong, or Dobbs is spreading, you know, fake news. He ... reported, you can decide? Peter Weber
