President Donald Trump (R-FL) has seen his approval rating among Republican voters drop to 39% [1].

The decline suggests a potential fracture in the president's core base, particularly within rural communities that have historically provided critical support.

The findings come from a Fox News poll conducted in May 2026, which surveyed 1,002 registered voters nationwide [1, 2]. This represents a significant shift in sentiment among the GOP constituency.

Analysts said that the economic impact of current geopolitical tensions is driving the trend. Higher agricultural costs stemming from the Iran war and the implementation of tariffs are reportedly eroding support among rural voters [3].

Wisconsin farmers are highlighted as a specific group experiencing this economic strain [3]. The intersection of trade policy and conflict-driven costs has created a volatile environment for agricultural producers, a demographic that often dictates the outcome of swing-state elections.

While the president has maintained a strong grip on the party for years, this 39% approval rating [1] marks a dire new low. The data indicates that the financial burden of tariffs is beginning to outweigh political loyalty in the U.S. heartland.

“Trump's approval rating among Republican voters has dropped to 39%”

The drop in approval among GOP voters indicates a shift where economic pragmatism is overriding partisan loyalty. Because rural voters in states like Wisconsin are pivotal for electoral success, the president's struggle with agricultural costs could signal a broader vulnerability in his coalition if trade and foreign policies continue to impact farm incomes.
