Haley's first big moment of the debate comes as she spars with Pence on abortion, but the moderators cut off their conversation before it really developed. Somewhat unexpectedly, Burgum stands out on abortion too, unequivocally coming out against a national abortion ban on constitutional grounds.

Members of DeSantis’s campaign are still upset about a debate memo that was prepared and published last week by a super PAC supporting the governor, a source close to the campaign told ABC News on Wednesday, describing those members of his team as “wildly irritated.”

Chief among the complaints is that the memo, which detailed suggested approaches and lines of attack, effectively handcuffs DeSantis by preventing the governor from using any of the advice on stage lest he invite attacks from opponents for using lines manufactured for him by other people.

The memo included research documents that show that Axiom Strategies, a consulting firm tied to the super political action committee, anticipated that the biggest hits to DeSantis would include his battle with Disney -- ABC News' parent company -- past comments on Ukraine, Florida's Black history standard, the culture wars and abortion.

The packet also included past comments made by presidential hopefuls attacking DeSantis on those specific subjects.

DeSantis himself has downplayed the memo, telling Fox News recently, “It’s not mine. I haven’t read it. It’s just -- I think it’s something that we have put off to the side.”

Abortion hasn't just been a losing issue at the ballot for Republicans: Since the Dobbs decision, more Americans are supporting more liberal views on abortion than they have in decades. More Americans want abortion to be legal in most cases, and more Americans are suspicious of restrictions. The share of Americans who want abortion to be legal in the first trimester is 60 percent, according to Gallup.

Haley was the first participant to name Trump during the debate, referring to the amount that was added to the nation's debt under the former president, who also oversaw the sweeping response to the unprecedented COVID-19 pandemic and a major tax cut.

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.
