HOUSTON — Ten Democratic presidential candidates squared off at a debate on Thursday night in Houston, where divisions over the path forward for the party were on full display.

Here’s a look at how the candidates fared over the course of three hours at Texas Southern University, listed by their standings in national polls.

Nothing happened on Thursday night to fundamentally change the nature of the race, making it a positive night for Biden, who has been running atop the field of Democrats for months now, even as many in Washington have braced for his collapse.

Biden was steady, up for a fight and avoided any of the embarrassing gaffes that have plagued him on the trail.

The conventional wisdom heading into the debate was that there was no need for the front-runner to go on the attack, but Biden came out swinging at Sens.

And if the three-hour debate was an endurance test for the 76-year-old, he seemed to grow stronger as the night wore on.

In the debate’s third hour, Biden vigorously went over his allotted time, after repeatedly cutting himself off in the prior debates.

“I’m going to go like the rest of them do, twice over,” Biden declared, in reference to other candidates who spoke beyond their allotted time.

One of Biden’s strongest moments came toward the end, when talked about the heartbreak he experienced in losing his wife and daughter to a car accident and his son to a brain tumor.

Sen. Bernie Sanders (I-Vt.)

But Sanders appeared to be hoarse or battling a cold, and it was a struggle for him at times to get his thoughts out with the usual emphasis.

And hitting the same notes from 2016 hasn’t been much of a winner for Sanders so far, as voters shop around for new options, such as Warren.

Still, Sanders was good for a few zingers as he drew a contrast between himself and Biden.

He repeatedly turned to the former vice president to say, “I strongly disagree, Joe.”

Sen. Elizabeth Warren (D-Mass.)

Warren was steady on Thursday night, sticking to the script and refusing to be drawn into a confrontation with Biden, who tried to pick a fight with her on Medicare for All.

Instead, Warren stayed focused on the themes that have propelled her into the top tier of candidates — income inequality, universal health care and student loan debt.

Warren could benefit from staying above the fray, as she had the appearance of a front-runner who won’t be drawn into intra-party squabbles.

All in all it was a strong night for Harris, who was more at ease in a debate where she didn’t seem pressured to be leading the attacks against Biden.

The California Democrat instead directed her ire at Trump, opening with a direct-to-camera statement to the president about how he had “used hate, division and fear” to distract from his “failed polices and broken promises.”

“Now you can go back to watching Fox News,” Harris quipped, provoking laughter from the audience.

Later, Harris said that “Trump didn’t pull the trigger” in El Paso, Texas, “but he’s been tweeting out the ammunition.”

And she likened Trump to the wizard in “The Wizard of Oz,” saying that when you pull back the curtain you see that “it’s a really small dude.”

Harris also adequately handled questions about her record as attorney general of California, arguing that she pursued that path in order to change the system from the inside.

Buttigieg was steady, but he was one of several candidates who seemed to be operating in the background all night.

The mayor had several strong moments, talking about his experience as a Navy intelligence officer in Afghanistan; the “generational theft of slavery;” and how he would level the playing field for racial minorities.

Buttigieg also sought to be the adult in the room, telling his rivals that their bickering was rendering the debates “unwatchable” and “reminding everyone why they hate Washington.”

But it seemed like his most memorable moment of the night was in response to tech entrepreneur Andrew Yang Andrew YangBiden's latest small business outreach is just ... awful Doctor who allegedly assaulted Evelyn Yang arrested on federal charges The Hill's Campaign Report: Biden weighs in on police shootings | Who's moderating the debates | Trump trails in post-convention polls MORE’s declaration that he’d give 10 people in the U.S. $10,000 this year as a test run for a universal basic income.

Buttigieg looked puzzled and said, “That’s original, I’ll give you that.”

Tech entrepreneur Andrew Yang

Yang is not a very polished public speaker, creating a negative contrast between himself and the more experienced debaters on stage next to him.

Instead, the tech entrepreneur has gotten this far by pluck, charm and media savvy.

On Thursday night, Yang grabbed headlines by telling viewers they could sign up on his website to be one of 10 families his campaign would give $12,000 this year as a case study for his proposed universal basic income.

Yang also proposed giving every citizen $100 “democracy dollars" to donate to campaigns, saying it would eliminate corporate influence over the electoral process.

Those ideas will likely drive huge numbers of people to his website, but probably won’t bring many new mainstream Democrats to his outsider campaign.

Still, it will be interesting to see if the insurgent buzz around him continues to grow, even as it baffles Washington insiders.

O’Rourke might have had one of the best nights of anyone on stage.

The Texas Democrat was in front of a friendly home crowd in Houston, and rival after rival lined up to praise his leadership on gun control after the racially-charged mass shooting in his hometown of El Paso last month.

O’Rourke leaned into his proposal for a “mandatory buyback,” which has split the Democratic field.

“Hell yes, we’re taking your AR-16 and your AK-47,” O’Rourke said. “It won’t be used to kill our fellow Americans any more.”

It may end up being too little too late for O’Rourke, whose fundraising has dried up as his poll numbers have stalled.

But for one night at least, O’Rourke reminded Democrats about his promise as a candidate who can connect on an emotional level with voters.

Booker earned scores of headlines for vigorously attacking Biden at the previous debates.

There was none of that on Thursday night, pushing Booker into the background for much of the debate.

Still, he had several strong moments that will remind Democrats about how he is an effective, quick-witted and charismatic communicator.

Booker repeatedly returned to personal stories about governing in the racially diverse city of Newark and about how the criminal justice system is “savagely broken.”

“Bernie wrote the bill, but I read it,” Klobuchar said.

Still, Klobuchar’s night was unremarkable overall and it’s tough to see her path to the nomination as she tries to sell herself as the pragmatic centrist in a race where Biden is dominating that lane.

Former San Antonio Mayor Julián Castro

Castro bet big that going after Biden would be his best path to become a top contender.

The attacks were praised by progressives eager to see Biden taken down, but many Democrats viewed the attacks as nasty, unnecessary and hitting below the belt.

Castro brought Biden’s age and mental acuity to center stage, repeatedly accusing the former vice president of forgetting what he’d just said.

Later, Castro accused Biden of embracing Obama when it helped him and refusing to take responsibility for Obama’s policies when it is inconvenient for him.

“I’m fulfilling the legacy of Barack Obama Barack Hussein ObamaDemocrats ramp up pressure on Lieberman to drop out of Georgia Senate race The Hill's Campaign Report: Biden on Trump: 'He'll leave' l GOP laywers brush off Trump's election remarks l Obama's endorsements Trump pledges to make Juneteenth a federal holiday, designate KKK a terrorist group in pitch to Black voters MORE and you’re not,” Castro said.

Still, it seems unlikely that voters will view Castro, rather than Biden, as Obama’s standard bearer.

And Castro’s attacks provoked bickering among the candidates, who warned that the debate was devolving into an “unwatchable” spectacle.

Castro defended the attacks.

“It’s called a primary election,” he said.
