A survey conducted in January 2025 by the
Associated Press and the
NORC Center for Public Affairs Research showed that 30 percent of Americans supported Kennedy's health agenda compared to 42 percent who disapproved, with support among conservatives being significantly higher. MAHA has been criticized by the mainstream medical community and news outlets, who have said that MAHA mixes promotion of healthy living with public health
conspiracy theories, citing the movement's close ties to the
anti-vaccine community. Critics have characterized the movement as a cult, with
The New Yorker describing Kennedy as being viewed as a faith healer who "should not be criticized; a vast conspiracy threatens the movement; triumph is ongoing, even if the movement's crusade against dangerous pesticides and heavy metals in the soil and drinking water has culminated in the election of a President who apparently loves all that stuff".
The New York Times described it as attracting a loose coalition of health-conscious moms,
men's rights activists, and some environmental groups. It described traditional environmentalists as being "wary" of MAHA's controversial positions on vaccines and other issues. A study of MAHA-related posts on social media found that the movement started overwhelmingly positive, but experienced a substantial decline following Kennedy's nomination (2024-11-14), subsequent confirmation (2025-02-13), and the introduction of MAHA-aligned legislation in Texas (2025-03-03), ultimately reaching a point at which opposition outweighed support on social media. Proposals of the movement, such as the increased regulation of food and pharmaceutical companies, received some early bipartisan support in late 2024 and early 2025, and were praised by Democratic
Colorado governor
Jared Polis and independent
Vermont senator
Bernie Sanders, despite both Polis and Sanders objecting to Kennedy's views on vaccines. Sanders called Kennedy's stance on the food industry "exactly correct" but described his broader health views as "extremely dangerous". In May 2025, the
Democratic National Committee (DNC) criticized MAHA for citing sources in the report that did not exist. White House press secretary
Karoline Leavitt told reporters Thursday that the citation errors were due to "formatting issues" and did not "negate the substance of the report." The errors were later updated. The DNC also referred to
Robert F. Kennedy Jr. as a conspiracy theorist, arguing that with his help, "Donald Trump is putting millions of Americans' health care and safety at risk." By late 2025,
Politico reported that increasing measles outbreaks and Kennedy and MAHA's anti-vaccine views were polling poorly with the public, with an October
KFF poll showing 40% of parents who identified with MAHA did not trust Kennedy to give reliable information on vaccines, compared to 75% of non-MAHA supporting parents. It described efforts by Democratic politicians to paint Kennedy as a "boogeyman" and use MAHA's views against Republicans in the 2026 elections, especially after such attacks appeared to contribute to the Democratic victory during the
2025 New Jersey gubernatorial election. ==Impact==
