Mr. Trump has exploited this dynamic, offering ideas that experts consider unworkable, but that tap into some voters’ desire for a strong-handed leader. Foreign policy, some research suggests, provided an ideal medium for this message.
Typically, candidates cannot reach the national stage without first proving their fitness to certain institutions that care deeply about foreign policy: the news media that vets them, the parties that provide them with crucial support, the policy makers they will need once in office.
Because foreign policy is so complex and most voters do not follow its particulars as closely as they do domestic issues, those institutions play an outsize role in shaping the bounds of acceptable debate.
But Mr. Trump, a celebrity who largely self-financed his primary campaign, was able to bypass this process, hacking the politics of foreign policy to his considerable advantage — and in ways that could outlast his candidacy.
A foreign policy not about foreign policy.
In a perfect world, each voter would dedicate months of study to the complexities of major global conflicts, evaluate the available options, then determine which candidate’s plan best balances risks and rewards.
In the world we live in, voters choose whom to believe based on whose message feels truest.
“We have overwhelming evidence that voters don’t know that much about the details of foreign policy,” explained Elizabeth N. Saunders, a George Washington University political scientist.
“People tend to choose the candidate they like first,” and then take on that candidate’s views as their own, she added. “This is the way people make sense of a complicated world.”
All candidates wrap their policy agendas in simpler values, such as strength or inclusiveness, or stories of heroes and villains, Professor Saunders said, “as a way of crafting a narrative that voters who don’t follow the details can grab on to.”
