Another prominent Florida Republican has publicly distanced himself from Donald Trump, days after María Elvira Salazar called out the US president’s immigration-enforcement policy targeting law-abiding undocumented immigrants.

Byron Donalds, the Republican nominee for governor in November’s US midterm elections, launched an updated campaign website on Tuesday that was stripped of almost every mention of Trump and removed a photograph of the congressman and his wife, Erika, posing with the president, the Miami Herald reported.

The move comes as Trump’s overall approval rating fell below 30% for the first time, dragged down by dissatisfaction over his handling of the US economy and the Iran war, and Republicans brace for heavy losses in November, including the possible loss of the party’s majorities in the US House of Representatives and Senate.

The Herald’s report was based on research by the website tracking service Visualping, which recorded multiple changes to the Donalds site, including the removal of at least eight mentions of Trump from its homepage.

Prior to the alterations, Donalds described himself as a “Trump-endorsed proven conservative fighter”, while other since-removed banners featured a “chip in to support Trump-endorsed Byron Donalds” fundraiser and one of Trump’s “run, Byron, run” endorsement announcements from last year.

A previous capture by Wayback Machine of the Donalds website’s list of issues features “Enact the Trump agenda” as his number one priority; that has now disappeared, replaced by “affordability”.

The only reference to Trump that still appears is his name among a rolling list of endorsements for Donalds by other conservative and rightwing figures, including Elon Musk, Rick Scott, Mike Johnson and the late Charlie Kirk.

The Donalds campaign did not respond to a request for comment.

Donalds clinched the Republican nomination for the election to succeed Florida’s incumbent governor, Ron DeSantis, in August. He has represented south-west Florida in Congress since 2021.

Politico reported on Monday that multiple Republican candidates in numerous November races are breaking with Trump, with mail-in ballots already sent out in some states and barely 40 days until 3 November.

“These candidates know how to read a poll,” a GOP strategist told the outlet. “They know he is kryptonite.”
