For the primary time in months, Gov. Ron DeSantis on Saturday confirmed the aggressive political instincts that his allies have lengthy insisted he would exhibit in a contest in opposition to 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 stories of attainable extreme climate.

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

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

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 outdoors 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 as we speak, however earlier than we went again to Florida we needed to return by and say hello to the folks of Des Moines,” a grinning Mr. DeSantis mentioned. “So thanks all for popping out. It’s a ravishing evening, it’s been an important 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 in opposition to previously, Mr. DeSantis moved to point out he doesn’t intend to undergo the identical end result.

“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 through which Mr. Rubio was criticized for not combating again sufficient in opposition to Mr. Trump.

Mr. DeSantis has been outflanked by Mr. Trump’s workforce at varied turns till now. Saturday was the primary time Mr. DeSantis has taken benefit of a possibility to point out up Mr. Trump over a perceived misstep.

Mr. DeSantis must string collectively many extra days like Saturday in a marketing campaign that can rely closely on profitable the Iowa caucus early subsequent 12 months. 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 Middle — populated by Christian conservatives whose help he should acquire — was seen as a optimistic growth 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 immediately till after he formally pronounces his marketing campaign, based on two folks aware of his political operation. And even when he does soar into the race, which is anticipated to occur imminently, he’ll largely deal with contrasting his report with Mr. Trump’s — significantly on points just like the coronavirus pandemic — whereas making the case that he’s the candidate higher outfitted to defeat President Biden in a normal election.

It’s a technique that avoids relitigating Mr. Trump’s false claims concerning the 2020 election, and one the governor is foreshadowing as he barnstorms Republican occasions across the nation. It additionally positions Mr. DeSantis — who’s many a long time youthful than the 76-year-old Mr. Trump, who was 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 couple of referendum on Joe Biden and his failed insurance policies, and we offer a optimistic different 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 point out his rally.

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

“I’d 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 point out off the typically enigmatic lighter facet of his character, flipping burgers on the picnic and speaking about his life as a household man together 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 performed 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 usually anticipated to produce. His spouse appeared to attempt to fill in these gaps, telling private tales about Mr. DeSantis’s childhood in Florida, his army service, and their three younger youngsters.

“When he will get residence, don’t assume for a second that he goes and goes proper to mattress,” she mentioned. “I hand three small youngsters over to him and I am 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 point out 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 a brilliant 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 referred to as off his personal occasion in the midst of the afternoon, citing a twister watch.

However though it rained closely at factors, it was sunny mid-afternoon and no extreme climate comparable 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 outdoors 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.”

Mr. DeSantis’s hope for a win within the Iowa caucuses includes 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 select up help from sufficient corners of the state to extend his help. As an 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.
