A newly released CNN poll, conducted this month, illustrates the resilience of a hawkish DNA within the Republican Party and among its voters even amid the rise of an isolationist strain that has sought to gain influence in the GOP during President Donald Trump’s second term.

The poll asked respondents: “Do you think the United States should or should not take the leading role among all other countries in the world in trying to solve international problems?” Overall, 43% took the more active approach, while 56% took a more isolationist view.

Republicans, however, remained the strongest advocates of a muscular American role in world affairs, with 52% supporting America taking a leading role and 47% opposed. By contrast, just 42% of Democrats and 39% of independents shared the more hawkish worldview.

Notably, the shift in more isolationist sentiment was almost entirely driven by Democrats and independents since the last CNN survey in March, which found majority support for significant American global engagement. In the March survey, a 57% majority of Democrats preferred more American involvement in the world, a number that dropped 15 points in the last four months. The Republican share of those preferring American engagement remained steady at 52%.

The results from the CNN polls suggest there’s a more committed core of Republican-voting hawks that is more resilient than the shifting political winds, whereas the Democratic foreign policy worldview appears more dependent on partisanship and what’s happening in the news at the time. 

In March, at the time of the first CNN poll, Democrats showed a surge of support for foreign engagement — in large part, because they were responding to the hostile reception Trump delivered at the time to Ukrainian President Volodymyr Zelensky, who was seeking American military aid to his country. Back then, Trump wrongly blamed Zelensky for causing the war, and attacked him as a dictator in the run-up to the ugly confrontation at the White House. It was the high point of isolationism in Trump’s second term — and prompted an uptick of hawkishness among Democrats.

But since then, Trump has sharpened his rhetoric against Russian President Vladimir Putin and agreed to send Ukraine offensive weapons, in a reversal of his previous reluctance. He also decided to strike Iran’s nuclear facilities despite alarmism from an isolationist faction within his party, which turned out to be a major military (and political) success. 

A recent Echelon Insights survey underscored that Trump’s hawkish turn has broadened and deepened support for strongly supporting American allies within the party. A clear 49-36% of Trump voters, asked if they supported continuing to give weapons to Ukraine, said yes. When informed that it was Trump’s decision to aid Ukraine further, nearly two-thirds of Trump supporters embraced the decision.

The actions on Capitol Hill are consistent with the polling. When Rep. Marjorie Taylor Greene (R-GA) proposed a series of amendments cutting off aid to foreign allies, the vast majority of Republicans voted against them. Even on her proposal to cut military aid for Ukraine, 141 of the 217 House Republicans took the pro-Ukraine side. 

And when Greene proposed to block missile defense funding that the U.S. gives to Israel, only one other Republican, Rep. Thomas Massie (R-KY), joined her. Indeed, there were more Democrats who joined with MTG (four) than Republicans — in a sign of the “horseshoe theory” of the far left and far right uniting in their extremism.

Trump’s decision to strike Iran’s nuclear program appears to have created a momentum shift within the party, pushing back the faction of isolationists seeking to gain influence in the administration but also building support for a familiar brand of muscular engagement that has defined the party for generations.
