"Despite what Purdue Pharma has done, their connection to the opioid crisis and the overdose deaths that we're seeing throughout this country, they've been able to act with complete impunity and pay no consequences, not a single night in jail," O’Rourke said at one point of the makers of the drug Oxycontin.

This is mostly false. While it's true that no executives from the company have gone to prison, the corporation behind the narcotic has paid hundreds of millions of dollars in fines and settlements over the years.

This year, for instance, Purdue Pharma paid $270 million in a settlement with the state of Oklahoma.

Just a couple of references were made to one of the pressing issues inside the Democratic Party. The party is increasingly dependent upon the votes of black and Latino voters but hires consultants and spends the bulk of its voter mobilization energy in pursuit of white, working class voters who began decamping for the Republican Party more than five decades ago.

The first reference emerged in Ryan's argument that a focus on "working class" American issues would unite various demographic groups and repair the party's reputation as a collection of coastal "elites." 

The second came in a question from moderator Rachel Maddow, who asked Klobuchar what she has done in her legislative career for the African Americans the party relies on to form its most reliable voter base.

Here are the closing statements from each candidate, summarized: 

Delaney: "We're so much better than this" ... "This is about getting America working again."

De Blasio: "Choose someone" who has experience like his as New York City mayor fighting for "working people."

Inslee: "If we do not have the next president" as someone who commits to climate change as his top priority, it will be a disaster.

Ryan: I've represented a forgotten community, this election is about bringing all of America together. Forgotten America will be heard.

Gabbard: Our country is about "service before self," we don't have that right now in our government.

Castro: I will work hard every single day to increase opportunity for all Americans. We will say "adios" to Trump.

Klobuchar: I get things done, that's my focus, and I have a track record. Also, I can win and beat Trump because of my history of winning in red districts.

Booker: I've taken on bullies and won. We win when we rise above the fray. Let's not fight at Trump's level.

O'Rourke: Can't return to the same old politics. The next generation needs to be at the forefront of U.S. policy.

Warren: I came from humble roots and know how hard it is to succeed. I'm fighting to open up that opportunity to everyone. "I will fight for you as hard as I fight for my own family."

"I’m someone that can win and beat Donald Trump. ... I have won in the reddest of districts," Klobuchar claimed in her closing statement. And it's true — Klobuchar carried a bulk of Minnesota counties during her 2018 re-election that Trump won in 2016.

Trump only lost Minnesota to Hillary Clinton in 2016 by 1.5 percentage points, yet Klobuchar won 60 percent of the vote in the state in 2018. Of the approximately 3,000 precincts (of 4,120 total) that voted for Trump in 2016, Klobuchar won about 1,250 of them, according to the Minneapolis Star Tribune.

Tim Ryan, in one of the night's few direct attacks on the Trump administration, faulted President Trump for failing to fill key roles at the State Department. The federal vacancies actually go beyond State. NBC News' Dareh Gregorian, in an article published in March, found that Trump had yet to nominate people for close to 140 top-level positions — something that experts said was hampering his long-term goals.

In the first direct question about the #LGBTQ community this Pride Month, Rep. Tulsi Gabbard was asked about her past anti-LGBTQ activities, like working for her father’s organization that advocated for same-sex marriage bans and “gay conversion therapy.” 

In response, Gabbard touted her vote for the Equality Act and said that she held views when young “that I no longer hold today.”

But Booker interjected: “This is not enough.”

“We do not talk enough about trans Americans, especially African American trans Americans, and the incredibly high rates of murder right now," Booker said.

The candidates have mostly shied away from attacking President Trump, mentioning his name sparingly. But they have also said relatively little about Trump's predecessor: Barack Obama. It doesn't seem tonight's contenders, even those who have embraced some of Obama's policies or complement him ideologically, are rushing to position themselves as the 44th president's spiritual heir.

That could leave the door open for Joe Biden tomorrow night.
