Poll: Majority of GOP Backs Trump, Some Differences on National Security Issues

July 18, 2016

As the Republican National Convention gets under way in Cleveland, a new survey by the Chicago Council on Global Affairs, conducted June 10-27, 2016, finds that a large majority of Republicans are now getting behind the GOP nominee. At the same time, there are some clear differences on certain issues related to national security between the core supporters of Donald Trump and those who wanted another candidate to win the party's nomination.

Trump Support

  • If the general election were held today, 83 percent of Republicans (including self-described Republicans and Republican-leaning Independents) say they would vote for Mr. Trump in the presidential contest against Secretary Clinton (13 percent).
  • But Mr. Trump was not the top choice for many Republicans among the full field of primary candidates. While a committed minority of 31 percent say that Trump is their “top choice for president,” 65 percent name a different candidate. While eventually deciding to back Trump, those who were hoping for a different nominee are not endorsing some of Trump’s key positions.
     

National Security

Republicans—and a majority of Americans across political affiliations—express a heightened sense of threat from terrorism after the Orlando shootings and think that a wide range of actions are effective in combating terrorism. Yet core Trump supporters (the 31 percent who name Trump as top choice among the field of primary candidates) differ on some key approaches.

  • Trump’s core supporters are more likely to believe that limiting the flow of refugees and migrants is effective at countering terrorism (86 percent vs. 74 percent among other Republicans). They are also more likely to say that using torture is effective (73 percent vs. 60 percent among other Republicans).
  • Core Trump supporters are somewhat less likely than Republicans who supported a non-Trump candidate to say that maintaining existing alliances is a very effective way to achieve U.S. foreign policy goals (34 percent vs. 42 percent). Similarly, only 44 percent of core Trump supporters say that NATO is essential to U.S. security, while a majority among those who backed other candidates (61 percent) say it is essential.
  • By very narrow majorities, Republicans supporting both Trump and non-Trump candidates say the country is less safe now than before the 9/11 terrorist attacks (54 percent and 51 percent respectively).
     


 

On the home front, there are no differences between Republicans supporting Trump or a non-Trump candidate on personal concerns about gun violence in the United States.

  • In contrast to Democrats, who personally worry about being a target of gun violence more than a target of a terrorist attack (61 percent vs. 41 percent among self-described Democrats and Democratic-leaning Independents), Republicans are no more concerned about one possibility over the other (46 percent gun violence, 50 percent terrorist attack).
  • Just over half of both Trump supporters (54 percent) and other candidate supporters (52 percent) say that the greater terrorist threat to the United States comes from people inside versus outside the country.
     

Immigration

Core Trump supporters favor policy stances that align with Mr. Trump’s positions on immigration. While the Republican public overall is much more concerned than Democrats and Democratic-leaning Independents about this issue, core Trump supporters express an even greater sense of threat and even less favorability toward immigrants:

  • 69 percent say that legal immigration should be decreased, compared to 45 percent among Republicans who supported a different candidate.
  • Core Trump supporters are nearly 20 percentage points less likely than other Republicans to express a favorable view of Middle Eastern (15 percent Trump vs. 38 percent non-Trump) and Mexican immigrants (35 percent Trump vs. 53 percent non-Trump) currently living in the United States.
  • 86 percent say that immigrants and refugees coming into the United States are a critical threat, compared to 56 percent of those Republicans who supported a non-Trump candidate.
  • Core Trump supporters are more likely to favor a wall expanding the 700 miles of border wall and fencing with Mexico to reduce illegal immigration into the United States (93 percent) versus a smaller majority of other Republicans (72 percent).
     


 

Trade and Globalization

Core Trump supporters also share the candidate’s anti-globalization and anti-trade dispositions.

  • They are considerably less likely than Republicans who supported a non-Trump candidate to say that international trade is good for the U.S. economy (40 percent core Trump vs. 57 percent other candidate), consumers like them (54 percent vs. 73 percent), and their own standard of living (49 percent vs. 65 percent).
  • Only 50 percent say that globalization is mostly good for the United States, compared to 62 percent of those that supported other candidates.
  • Only 47 percent support the Trans-Pacific Partnership trade agreement, while a majority of those who supported other candidates (58 percent) favor signing the deal.
  • While protecting American jobs is a top priority for Americans, it ranks highest among core Trump supporters (86 percent say it is very important, compared to 72 percent of Republicans who supported other candidates).
     

Methodology

The analysis in this report is based on data from the 2016 Chicago Council Survey of the American public on foreign policy. The 2016 Chicago Council Survey was conducted by GfK Custom Research using their large-scale, nationwide online research panel between June 10-27, 2016 among a national sample of 2,061 adults, 18 years of age or older, living in all 50 U.S. states and the District of Columbia. The overall margin of error ranges ±2.2 to ±3.5 percentage points, depending on the specific question. For the analysis among Republicans included here, the margin of error ranges from ±7.9 to ±11.2 percentage points, again varying depending on the specific question.

Unless specified otherwise, references to Republicans in this report refer to those who self-identified as Republican and those who self-identified as an Independent that is “closer to the Republican party.”

Respondents were asked two separate questions about voting preferences. The first asked: “If the presidential election were being held today and the candidates were Hillary Clinton, the Democrat or Donald Trump, the Republican, for whom would you vote?” The response categories were randomized. The second question, which we used to calculate “core Trump voters,” asked: “Regardless of your voting preference in the previous question, who was your top choice for president among the following candidates – Hillary Clinton, Donald Trump, Bernie Sanders, Ted Cruz, John Kasich, Marco Rubio, Jeb Bush, or other (specify)?” These response options were also randomized.

The 2016 Chicago Council Survey is made possible by the generous support of the John D. and Catherine T. MacArthur Foundation, the Korea Foundation and the personal support of Lester Crown and the Crown family.
