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.

Trump maintains a lead of 25 percentage points over his nearest competitor in Iowa, according to the latest polls.

DeSantis and Scott are both polling higher in Iowa than they are nationally, according to our polling average. Trump is polling about 10 points lower in Iowa than in national polls.

According to a July poll from J.L. Partners/DailyMail.com, only 51 percent of Iowa Republicans said their mind was made up. Forty-three percent said they could still be persuaded to support another candidate. Voters who said they plan to vote for Trump were the most likely to say their mind is made up, with 80 percent saying so compared with 37 percent of those who said they plan to vote for DeSantis and 11 percent of those who said they plan to vote for Scott.

Scott and DeSantis have the highest net favorability among Iowa Republican voters. Pence, Christie and Hutchinson are underwater.

In an early state poll from the Manhattan Institute conducted in July, Iowa Republicans are split on whether electability is important. Forty-six percent of Iowa Republican voters say that it is most important for Republican candidates to win elections and be in power, even if that means compromising or moderating their positions, while 45 percent said it is most important for candidates to stay true to their principles, even if that means losing elections.

Iowa Republicans also think that skipping primary debates shows weakness more than strength, according to a July Fox Business/Beacon Research/Shaw & Co. Research survey. Fifty-nine percent of Republicans said skipping the debate shows weakness, while 27 percent said it shows strength.
