Gov. Ron DeSantis’s marketing campaign shared a provocative video on Friday attacking the report of former President Donald J. Trump relating to L.G.B.T.Q. folks that was broadly condemned as homophobic, together with by a distinguished group representing homosexual and lesbian Republicans.

The video, posted on Twitter by the “DeSantis War Room” account, opens by exhibiting Mr. Trump proclaiming, “I will do everything in my power to protect our L.G.B.T.Q. citizens.” Mr. Trump made these remarks on the Republican National Convention in July 2016, after invoking the horror of the Pulse nightclub taking pictures the earlier month. The bloodbath, at a preferred homosexual nightclub in Orlando, in Mr. DeSantis’s residence state of Florida, left 49 individuals lifeless.

The video goes on to point out Mr. Trump expressing assist for transgender individuals utilizing the bogs of their alternative. It then makes an attempt to distinction Mr. Trump’s place with the hard-line stance of Mr. DeSantis, abruptly transitioning right into a jarring sequence of pictures of Mr. DeSantis (together with one with lasers taking pictures out of his eyes) which can be interspersed with right-wing web memes (the smiling, closely muscled man recognized on-line as “GigaChad”), news headlines (“Pride event in St. Cloud canceled after DeSantis signs ‘Protection of Children Act’ into law”) and popular culture references (amongst them pictures of the titular character from the movie model of the serial killer narrative “American Psycho”).

The DeSantis group shared the video the identical day that the Supreme Court ruled in favor of a Christian net designer who refused to create wedding ceremony web sites for same-sex {couples}, placing the rights of L.G.B.T.Q. individuals on shaky authorized footing.

Mr. DeSantis has often forged himself as a lightning rod for unfair criticism by liberals and has used such assaults to rally assist from his political base. The video, compiled by another Twitter user, appeared meant, partly, to draw extra liberal outrage at a time when he’s struggling to achieve traction in polls in opposition to Mr. Trump.

It was the kind of transfer — devised to impress a response — that Mr. Trump usually deployed from his Twitter account throughout the 2016 marketing campaign.

Earlier in his profession, as a congressman, Mr. DeSantis didn’t appear consumed by combating the L.G.B.T.Q. neighborhood. At the time, he privately told a counterpart he didn’t care about individuals’s sexuality.

And when he first ran for governor 5 years in the past, Mr. DeSantis advised he would take a extra reasonable strategy on some L.G.B.T.Q. rights points, saying that Republicans wanted to maneuver past debating which bogs transgender individuals ought to use. “Getting into bathroom wars, I don’t think that’s a good use of our time,” he said at a Republican candidate discussion board in 2018.

But on this marketing campaign for the Republican nomination, Mr. DeSantis has sought to spotlight — and develop — his ultraconservative credentials in an effort to place himself to the suitable of his chief rival.

The new video drew criticism not solely from Democrats but in addition from some in his personal celebration, together with the Log Cabin Republicans, which describes itself because the nation’s largest group for “L.G.B.T. conservatives and allies.” The group, which endorsed Mr. Trump in 2019 and has used his Mar-a-Lago membership for occasions, called the video “divisive and desperate” and stated it “ventured into homophobic territory.”

Sarah Longwell, a reasonable Republican political strategist, wrote on Twitter: “The consultants who think this kind of ‘running to Trump’s right’ is going to be effective should be sacked.” And Adam Kinzinger, a former Republican congressman and Trump critic, stated, “Outrage after outrage is the only way these guys know how to campaign.”

Mr. DeSantis’s marketing campaign shared the video on Twitter with the textual content: “To wrap up ‘Pride Month,’ let’s hear from the politician who did more than any other Republican to celebrate it,” referring to Mr. Trump.

Mr. Trump, who grew up in liberal New York and was a businessman for many years, was seen throughout his 2016 marketing campaign by some Republicans as extra open to the L.G.B.T.Q. neighborhood. But he additionally selected Mike Pence, then the governor of Indiana and a staunch conservative who had signed right into a legislation a spiritual freedom act that was seen as hostile to L.G.B.T.Q. individuals, as his operating mate. As president, Mr. Trump systematically dismantled L.G.B.T.Q. protections put in force by President Barack Obama, notably these regarding transgender individuals.

The video shared by the DeSantis marketing campaign displays a race to the suitable on a variety of points within the main. In Florida, Mr. DeSantis has signed bills limiting classroom instruction on sexual orientation and gender identification, punishing companies that admit minors to “adult live performances” akin to drag shows and making it a misdemeanor trespassing offense for individuals to make use of bogs in public buildings that don’t correspond to their intercourse at delivery.

And with its barrage of references to obscure right-wing memes, the video additionally reveals how closely Mr. DeSantis’s marketing campaign has leaned into the brash and provocative parlance of fringe on-line conservatives. The Florida governor, who’s operating properly behind Mr. Trump in nationwide polls, signaled from the start of his marketing campaign that he hoped to attach with right-wing voters on-line, together with by asserting his candidacy in a glitchy livestream occasion on Twitter with Elon Musk.

But by overtly courting such insular conservative communities, Mr. DeSantis, who has told donors that he’s the one Republican who can beat President Biden, might danger alienating the extra reasonable voters he’ll probably want in a common election.

The video additionally dangers laying aside some Republican donors, a few of whom are extra reasonable on points like L.G.B.T.Q. rights and are watching to see how Mr. DeSantis progresses earlier than committing to his candidacy.

In addition to implicitly evaluating Mr. DeSantis to Christian Bale’s homicidal character in “American Psycho,” who within the e-book is a mega-fan of then-businessman Donald J. Trump, the video — set to a thrumming bass — with out a lot rationalization additionally highlights Leonardo DiCaprio’s position as a hedonistic, drug-addicted monetary fraudster within the movie “The Wolf of Wall Street,” in addition to Brad Pitt’s depiction of Achilles in “Troy.” (Achilles, the hero of “The Iliad,” was usually portrayed in later Classical Greek literature because the lover of his male companion, Patroclus.)

For his half, Mr. Trump famous final month, sounding happy, that the difficulty of limiting rights for transgender individuals had turn into a significant animating pressure for conservative Republican voters.

“It’s amazing how strongly people feel about that,” Mr. Trump stated throughout a speech in North Carolina in June. “I talk about transgender, everybody goes crazy. Five years ago, you didn’t know what the hell it was.”
