Pence and Ramaswamy engaged in the first fiery back-and-forth of the night, with the former vice president going after the entrepreneur in an unprompted attack.

"You got people on this stage that won't even talk about issues like Social Security and Medicare," Pence said. "Vivek, you recently said, a president can't do everything. Well, I got news for you … the president of the United States has to confront every crisis facing America. I will put our nation back on the path to growth and prosperity and restore fiscal responsibility."

Ramaswamy didn't directly take Pence on in response, saying he'd tap into all of America's energy resources.

Pence didn't let Ramaswamy off the hook, firing back, "Let me explain it to you. I'll go slower this time."

Burgum finally gets a word in, and starts with an easy "break a leg" joke. Notable that he pivots pretty quickly from the economy write large to specifically talk about energy. He's come armed with the statistics you'd expect from the leader of one of the top energy-producing states in the union.

Haley, in her first remarks on stage, attacked her fellow Republicans for contributing to what she called runaway spending. She said that Pence, Scott and DeSantis all voted to increase the debt through various pieces of legislation.

"What I care about the fact is that no one is telling the American people the truth," Haley said. "The truth is that Biden didn’t do this to us, our Republicans did this to us, too."

She added, "I think it's time for an accountant in the White House."

Pence, in response to a question about how he supported major spending packages as vice president, pointed to his experience as proof he's ready to take on the top job.

"I must say you with all due respect to all of my friends on the stage, and even to one that’s probably looking on, I think unquestionably I am the best prepared, the most tested, the most qualified and proven conservative in this race," he said.

DeSantis revels in his record of snubbing public health recommendations to curb the spread of COVID-19. But he largely omits the closures of schools and businesses that happened under his watch.

Seven states did not issue stay-at-home orders to their residents, but not Florida.

On April 1, 2020, DeSantis issued an executive order directing all Florida residents to "limit their movements and personal interactions outside of their home." The order expired April 30, 2020, and Florida began a phased reopening in May.

Though he carved out an exception for religious services and some recreational activities, DeSantis didn't exempt in-person classroom instruction. DeSantis' Department of Education issued a March 13 recommendation that Florida schools close their facilities for an extended spring break before lengthening the closure through the end of the school year in early June.

Schools reopened in person in August 2020.

DeSantis remains Trump’s closest challenger, but his support has been dropping over the past several months: He currently trails the former president by nearly 40 percentage points in our national polling average.

With that drop have come some shake-ups in the DeSantis campaign. The campaign has laid off around one-third of its 92-person staff, with the latest cuts coming in July, according to ABC News. Changes stretched all the way to the top: DeSantis replaced his campaign manager with his governor’s office chief of staff. On top of that, some of his top donors have voiced concerns, saying they want DeSantis to recruit more major donors and take a more moderate approach on social issues.

All of that has made this debate crucial for DeSantis, both in terms of trying to chip away at Trump’s lead and proving to his supporters that he actually has a shot. He’s recruited a veteran debate coach and is getting advice from a supportive super PAC, according to The New York Times. That advice? Rather than attack the front-runner, DeSantis should “take a sledgehammer” to Ramaswamy who, unlike DeSantis, is rising in the polls. DeSantis won’t just be trying to win the debate tonight: He’s also aiming to push back against the rolling tide of news that hints at a flailing campaign.
