In the Senate, lawmakers who built reputations as leaders on foreign policy — like Mr. McCain and Senators Richard Lugar and John Warner — are long gone. Mr. Trump defenestrated much of the party’s policymaking establishment by alienating dozens of foreign policy experts, who refused to support his campaign, let alone enter his administration.
And for ambitious Republican officials, the political calculation remains stark: To the extent that Republican voters care at all about foreign policy issues, many have come to embrace Mr. Trump’s nationalistic views on issues like trade, overseas military ventures and even Russia.
Yet chances that Republicans will achieve a complete restoration of the traditional party platform seem low, particularly if Mr. Trump continues to flex his political power among his base. The former president captured the hearts and minds of his followers, shifting opinions on issues of globalism. During his administration, polling showed Republican voters adopted a more positive view of Russia and became more skeptical of trade agreements and international alliances.
A survey conducted by the Chicago Council on Global Affairs last year found that Republican voters preferred a more nationalist approach, valuing economic self-sufficiency, and taking a unilateral approach to diplomacy and global engagement
When asked about the effects of the coronavirus pandemic, 58 percent of Republicans surveyed said the outbreak showed the United States should be less reliant on other countries, compared with just 18 percent of Democrats who said the same. Close to half of Republicans agreed that “the United States is rich and powerful enough to go it alone, without getting involved in the problems of the rest of the world,” and two-thirds said they preferred that the country produce its own goods, as opposed to buying or selling overseas.Another survey by Tony Fabrizio, one of Mr. Trump’s pollsters, found that only 7 percent of Republicans prioritize national security and foreign policy issues, compared with nearly a quarter who care about economic issues.
