The 2017 Chicago Council Survey, conducted roughly six months into the Trump administration, tested the appeal of these ideas among the American public. The results suggest their attraction remains limited. For now, public criticism of trade deals, support for withholding U.S. security guarantees from allies, and calls for restricting immigration mainly appeal to a core group of Trump supporters (defined in this report as those Americans with a very favorable view of President Trump). Yet, aside from the president’s core supporters, most Americans prefer the type of foreign policy that has been typical of U.S. administrations, be they Republican or Democrat, since World War II. . . .
Indeed, in key instances, Americans have doubled down on these beliefs. Public support has risen to new highs when it comes to willingness to defend allies, the perceived benefits of trade, and a desire to grant undocumented workers a path to citizenship.
