Hutchinson has been critical of Trump since entering the race, calling on him to drop out, especially after his indictments. He pushed back against the loyalty pledge to support the eventual nominee, and tonight did not raise his hand when asked if he would support the nominee. "Over a year ago I said Donald Trump was morally disqualified from being president," he said tonight, to boos from the audience.

In talking about the weaponization of the Department of Justice, Scott trotted out a line he’s used before — that parents at school board meetings, “they’re called, under this DOJ, domestic terrorists.”

That’s False.

In 2021, Attorney General Merrick Garland issued a memo directing the FBI to address violent threats against school board members. The memo never called concerned parents "domestic terrorists," and maintained that "spirited debate" surrounding school policy is protected by the U.S. Constitution. A lawsuit against Garland also found that parents’ rights had not been violated.

When asked if he'd support Trump as the party's nominee if the former president were convicted, Christie said he would not, saying "the conduct is beneath the office of the president of the United States."

Hutchinson also indicated he would not support Trump.

In a January survey by YouGov/The Economist, 70 percent of Republicans said they strongly or somewhat supported Congress investigating charges of weaponization of the FBI and Justice Department. Eleven percent strongly or somewhat opposed a congressional investigation, and 19 percent were unsure.

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.
