President Trump worked the phones to give a boost to the Republican candidate in the race for Michael Waltz's former district.

Waltz resigned to be Trump's national security adviser in January, triggering a special election in Florida's 6th district, which includes Daytona Beach on the state's eastern coast. Republicans are concerned that the race, which falls on Tuesday, is closer than it should be.

Although Trump won the 6th district by 30 points in November, Republican state senator Randy Fine is edging out Democrat Josh Weil within the margin of error, and Weil leads in fundraising by a significant margin.

Democrats are still unlikely to flip the seat, but a strong performance in the deep-red district could help interrupt the doom-and-gloom narrative that has plagued the party since Trump's triumph in November.

Trump boosts Waltz replacement

The GOP is less worried about Tuesday's special election in Florida's 1st district, formerly represented by Matt Gaetz, who resigned to pursue a short-lived attorney general bid. Still, Trump is leaving nothing up to chance.

Trump won Florida by double digits in the fall, solidifying the former swing state's transformation into a MAGA stronghold. But Trump won't be running for re-election again, to the detriment of Republicans hoping to ride his coattails down-ballot. Special elections add another element of uncertainty that has Republicans anxious about Fine's campaign, with critics saying he isn't closing the deal.

And so, Trump came to the rescue on Thursday, praising Fine as an early supporter of his 2024 presidential campaign.

"That's why Randy will always have a very open door to the Oval Office. He will be there whenever I need him, and he wants to be there whenever we need him. He wants to be there for you," Trump said.

The president also offered words of support for Florida Chief Financial Officer Jimmy Patronis, saying he will win the 1st district "by a lot."

"The 1st Congressional District is special, and I won it by a lot, and Jimmy is going to win it by a lot. And remember, you're five days away from this all important special election taking place in your district on Tuesday, April 1, so April Fool's Day. So it's going to be the fool for the Democrat candidate, who happens to be terrible," Trump said.

Uncertainty looms

The president's intervention in Florida came as he yanked the nomination of New York Rep. Elise Stefanik (R) to be U.N. ambassador, citing concerns about the House.

Republicans have a 218-213 majority in the lower chamber of Congress, leaving little room for error as they aim to advance Trump's ambitious agenda.

Stefanik was supposed to resign from the House after the Florida races on April 1, but Trump does not want to take any chances on a special election in her district.

At the White House Friday, Trump said Stefanik was doing him a "big favor" by staying in Congress as he pointed to uncertainty over the GOP's fundraising in Florida.

"You never know what happens in a case like that,” he added.
