Fast food chain Steak n’ Shake is celebrating its political endorsement success after Zach Lahn, the candidate it supported for Iowa governor, won the GOP primary against Trump-backed Rep. Randy Feenstra by a narrow margin of less than 1 point. The company took to social media platform X to declare its '100% accuracy in political predictions,' linking its endorsement to its commitment to serving quality food. Lahn, who ran on a platform advocating for the transition away from toxic chemicals, received backing from MAHA PAC, a group aligned with Health and Human Services Secretary Robert F. Kennedy Jr. This primary result marks a significant loss for Trump in the 2026 midterm election cycle. Steak n’ Shake has also been revamping its menu to align with Kennedy's health initiatives, now using 100% grass-fed beef and beef tallow for cooking, while eliminating seed oils and microwaves. The chain aims to promote what it calls 'real food' and return to traditional fast food values.
