For the primary time in months, Gov. Ron DeSantis on Saturday confirmed the aggressive political instincts that his allies have lengthy insisted he would reveal in a contest towards former President Donald J. Trump.

After headlining two profitable political occasions in Iowa, Mr. DeSantis made an unscheduled cease in Des Moines — a transfer geared toward highlighting the truth that Mr. Trump had abruptly postponed a deliberate Saturday night rally within the space due to reviews of potential extreme climate.

Mr. Trump’s clarification for suspending the occasion drew skepticism from native Iowa officers and derision from DeSantis allies in regards to the “stunning” climate. And Mr. DeSantis — who has averted direct battle with Mr. Trump — basically kicked sand within the former president’s face by coming to an space that Mr. Trump claimed to have been advised was too harmful for him to go to.

After wrapping up his occasions on Saturday night elsewhere within the state, Mr. DeSantis headed to Jethro’s BBQ Southside, the place he and his spouse, Casey DeSantis, stood on a desk exterior and spoke to a cheering crowd. The barbecue joint was a brief drive from the place Mr. Trump had deliberate to host his personal rally.

“My higher half and I’ve been capable of be throughout Iowa right now, however earlier than we went again to Florida we wished to come back by and say hello to the folks of Des Moines,” a grinning Mr. DeSantis mentioned. “So thanks all for popping out. It’s a lovely evening, it’s been an awesome day for us.”

Mr. DeSantis’s pointed pit cease was a transparent rebuke to Mr. Trump, who has tried to torment the Florida governor for months, mocking him for his falling ballot numbers and perceived dearth of charisma. Mr. DeSantis’s resistance to hitting again whereas not a declared candidate as he completed the state’s legislative session, mixed with a handful of unforced errors, had allowed the previous president to take management of the race for 2024 and pissed off a few of Mr. DeSantis’s allies.

However as he prepares to tackle Mr. Trump, who has dominated each Republican he has campaigned towards prior to now, Mr. DeSantis moved to indicate he doesn’t intend to undergo the identical consequence.

“If somebody’s punching you within the face, you higher punch them again,” mentioned Terry Sullivan, who managed the 2016 presidential marketing campaign of Senator Marco Rubio of Florida — a race during which Mr. Rubio was criticized for not combating again sufficient towards Mr. Trump.

Mr. DeSantis has been outflanked by Mr. Trump’s staff at numerous turns till now. Saturday was the primary time Mr. DeSantis has taken benefit of a chance to indicate up Mr. Trump over a perceived misstep.

Mr. DeSantis must string collectively many extra days like Saturday in a marketing campaign that may rely closely on successful the Iowa caucus early subsequent yr. However Republican activists within the state say there’s a gap with caucus-goers for somebody apart from Mr. Trump. And the go to Saturday, the place he additionally traveled to Sioux Heart — populated by Christian conservatives whose help he should acquire — was seen as a constructive improvement by Republicans who wish to defeat Mr. Trump however have been dismayed by Mr. DeSantis’s stumbles as he steps onto the nationwide stage.

Regardless of the unexpected — albeit oblique — jab at Jethro’s, the governor is unlikely to criticize Mr. Trump instantly till after he formally pronounces his marketing campaign, based on two folks acquainted with his political operation. And even when he does leap into the race, which is anticipated to occur imminently, he’ll largely concentrate on contrasting his document with Mr. Trump’s — notably on points just like the coronavirus pandemic — whereas making the case that he’s the candidate higher geared up to defeat President Biden in a normal election.

It’s a method that avoids relitigating Mr. Trump’s false claims in regards to the 2020 election, and one the governor is foreshadowing as he barnstorms Republican occasions across the nation. It additionally positions Mr. DeSantis — who’s a long time youthful than the 76-year-old Mr. Trump, who was just lately indicted and faces the potential for further ones in different investigations — as sooner or later and never the previous.

“If we make this election a few referendum on Joe Biden and his failed insurance policies, and we offer a constructive various to take America in a brand new route, I believe Republicans will win throughout the board,” Mr. DeSantis mentioned at a Saturday night fund-raiser for the Republican Celebration of Iowa in Cedar Rapids. That occasion was proven on Fox Information throughout time that Mr. Trump had claimed Fox Information was reserving to indicate his rally.

Mr. DeSantis’s message is already interesting to some voters, together with Amy Seeger, who traveled from Milwaukee to see him converse earlier within the day at a picnic in Sioux Heart.

“I might vote for a shoe over Trump,” Ms. Seeger mentioned in an interview. “It’s time to transfer ahead. Trump could be very wrapped up in 2020 and enjoying the sufferer.”

Mr. DeSantis additionally used the Iowa journey to indicate off the typically enigmatic lighter facet of his persona, flipping burgers on the picnic and speaking about his life as a household man along with his spouse on the night fund-raiser in Cedar Rapids.

At that second occasion, Ms. DeSantis joined her husband on stage for an interview carried out by the state Republican Celebration chair, Jeff Kaufmann, following remarks from the governor. Mr. DeSantis’s stump speech focuses virtually completely on coverage, leaving out the biographical particulars that politicians are typically anticipated to produce. His spouse appeared to attempt to fill in these gaps, telling private tales about Mr. DeSantis’s childhood in Florida, his navy service, and their three younger youngsters.

“When he will get residence, don’t suppose for a second that he goes and goes proper to mattress,” she mentioned. “I hand three small children over to him and I’m going to mattress.”

The second resonated with the group. “There was a young facet to him, a household facet, that I didn’t actually have an appreciation for,” mentioned Bob Carlson, a doctor from Muscatine who was within the viewers.

As Mr. DeSantis builds towards an announcement, he’s starting to indicate different indicators of political power in ways in which matter past having monetary backing. The outing to Iowa — the place he’s anticipated to make a return go to pretty quickly — got here as an excellent PAC backing his all-but-official presidential marketing campaign introduced help from 37 state lawmakers. Native elected officers are likely to pay much less consideration to nationwide polls than members of Congress, who’ve been slower to endorse the governor.

In distinction, Mr. Trump — who had scheduled a rally to attempt to blot out Mr. DeSantis’s go to by showing on the identical day — abruptly known as off his personal occasion in the midst of the afternoon, citing a twister watch.

Steven Cheung, a spokesman for Mr. Trump’s marketing campaign, mentioned the Iowa occasion was bought out however that “because of the Nationwide Climate Service’s Twister Watch in impact in Polk and surrounding counties, we have been sadly compelled to postpone the occasion. We can be there on the first out there date.”

However though it rained closely at factors, it was sunny mid-afternoon and no extreme climate equivalent to a twister materialized, which raised questions amongst Iowans about whether or not Mr. Trump was involved he would fail to attract the group he had anticipated. The shortage of harmful storms was famous by native activists who wish to see the occasion transfer on from Mr. Trump.

“We’re all exterior on a pleasant evening,” the influential podcast host Steve Deace wrote on Twitter from the scene of Mr. DeSantis’s barbecue victory lap. “Fairly massive crowd too. No extreme climate in sight. Planes touchdown and taking off as scheduled.”

Whereas Mr. Trump canceled his Iowa look, he later known as in to an occasion hosted by the ReAwaken America Tour, a Christian nationalist, far-right motion led by Lt. Gen. Michael T. Flynn, the QAnon promoter and nationwide safety adviser who Mr. Trump compelled out early in his time period. The group, which helps promote conspiracy theories, paid certainly one of Mr. Trump’s golf equipment in Florida, the Doral, to carry it there.

Mr. DeSantis’s hope for a win within the Iowa caucuses entails uniting a cautious coalition of social conservatives who backed candidates like Rick Santorum and Mike Huckabee in 2016, together with suburban moderates who went for Mr. Rubio.

But Mr. DeSantis could also be poised to choose up help from sufficient corners of the state to extend his help. For example, the influential social conservative chief Bob Vander Plaats has met with the governor and has praised him publicly.

Mr. DeSantis’s day was additionally punctuated with appearances with Senator Joni Ernst and Gov. Kim Reynolds, each Iowa Republicans. These visits don’t essentially imply endorsements from these officers are within the offing, however they do point out a willingness within the state to help somebody apart from Mr. Trump and fewer concern than as soon as existed about retribution from the previous president.
