Elon Musk's image has lost some of its luster with Republicans since the tech billionaire's messy public falling-out with President Donald Trump last week, a new survey finds. Fewer Republicans view Trump's onetime government efficiency bulldog “very favorably” compared to April, according to the new poll from The Associated Press-NORC Center for Public Affairs Research. Though most Republicans continue to hold a positive view of Musk, their diminished fervor suggests his vocal opposition to Trump's signature spending and tax-cut legislation — and Musk's subsequent online political and personal taunts — may have cost him some enthusiasm within the party. Musk's overall popularity hasn't shifted, the poll found, and most of the shift among Democrats and Republicans was between “very” and “somewhat” strong opinions. Americans are less likely to view him favorably than his electric vehicle company, Tesla. That said, about half of Americans have a negative opinion of Tesla, highlighting another challenge for Musk at a time when the company has dropped in value and been the target of protests in the U.S. and Europe. About one-third have a favorable view of Tesla, while about 2 in 10 don't know enough to say. Even a subtle shift in the intensity of Republicans’ feelings about Musk could be important as the electric car and aerospace mogul weighs a second political act after spending about $200 million in service of Trump’s election effort last year. After decrying the GOP’s massive tax and budget policy bill as “a disgusting abomination,” Musk wrote on the social media platform, “In November next year, we fire all politicians who betrayed the American people.” The new poll suggests the messy feud with Trump may have rubbed some Republicans the wrong way, as the share of Republicans viewing him as “very favorable” has dropped from 38% in April to 26% now. At the same time, antipathy toward Musk among Democrats has waned a little. About two-thirds, 65%, of Democrats have a very negative view of Musk, down slightly from about three-quarters, 74% in April. Musk's bitter back-and-forth with Trump has business implications too. The company was already struggling with a backlash against Musk's association with Trump. Tesla sales across Europe plunged by half in May, even as growth in the electric car market accelerated. Then the company's shares plunged in value when Musk began sparring publicly with the president. While the intensity of people's feelings about Musk may have changed, their overall opinions have not. About one-third of U.S. adults have a favorable opinion of Musk, compared to about 6 in 10 who hold an unfavorable view, while about 1 in 10 don't know enough to say. That's unchanged from the April poll. The most recent poll was conducted June 5-9, after Musk left his government role and began attacking Trump's marquee legislative priority. Musk's public clash with Trump began just four days after Trump honored Musk effusively during an Oval Office event discharging him from duties as the head of the so-called Department of Government Efficiency. After first tearing down the budget bill, Musk two days later complained he had never seen the language, and aimed his fire at Trump, suggesting the president didn't sufficiently appreciate the role the billionaire assumed as the chief benefactor to Trump's reelection effort. “Without me, Trump would have lost the election, Dems would control the House and Republicans would be 51-49 in the Senate,” Musk wrote. “Such ingratitude.” Musk went on to claim without evidence that the federal government was concealing information about Trump's association with infamous pedophile Jeffrey Epstein. Musk deleted the post, and early Wednesday stepped back from his attacks on Trump, writing on X that he regretted "some of my posts, and that they “went too far.”
