A national survey promoted by President Donald Trump may not show that “50% of Americans AGREE that Robert Mueller’s investigation is a Witch Hunt,” as he tweeted.

The Suffolk University/USA Today survey, taken March 13-17, asked the following: “President Trump has called the Special Counsel’s investigation a ‘witch hunt’ and said he’s been subjected to more investigations than previous presidents because of politics. Do you agree?”

Of the 1,000 registered voters questioned, 50.3 percent of them answered “yes”; 46.8 percent said “no”; 2.7 percent were “undecided”; and 0.2 percent “refused” to answer.

But it’s not clear which of Trump’s claims respondents were agreeing or disagreeing with — that the Russia investigation is a “witch hunt,” or that there have been more politically motivated investigations of Trump than other presidents.

The survey question is “flawed,” Timothy Johnson, a past president of the American Association for Public Opinion Research, told us in an interview.

Other recent polls indicate that Americans have a more favorable opinion of Mueller’s investigation into possible collusion between the Russian government and Trump’s 2016 presidential campaign.

A CNN poll published in February found that 58 percent of respondents said Russia’s election interference is “a serious matter that should be fully investigated,” while 37 percent said the Mueller investigation is “mainly an effort to discredit Donald Trump’s presidency.”

In addition, a Washington Post/Schar School poll published last month found that 57 percent of adults thought “Mueller is mainly interested in (finding out the truth),” while 36 percent said he is “mainly interested in (hurting Trump politically).”

Trump, who has repeatedly referred to the nearly two-year-long investigation as a “witch hunt,” sent his tweet after the Suffolk University/USA Today poll results were released March 18.

Wow! A Suffolk/USA Today Poll, just out, states, “50% of Americans AGREE that Robert Mueller’s investigation is a Witch Hunt.” @MSNBC Very few think it is legit! We will soon find out? — Donald J. Trump (@realDonaldTrump) March 18, 2019

USA Today published an article about the results that carried the headline “Poll: Half of Americans say Trump is victim of a ‘witch hunt’ as trust in Mueller erodes.”

But the responses were based on a problematic survey question, some experts say.



Again, the survey asked: “President Trump has called the Special Counsel’s investigation a ‘witch hunt’ and said he’s been subjected to more investigations than previous presidents because of politics. Do you agree?”

“The first problem is that it’s a double-barreled question,” said Johnson, who is also the director of the Survey Research Laboratory and professor of public administration at the University of Illinois at Chicago. A double-barreled question is one that asks respondents to answer two questions at once.

Are they being asked if they agree that the investigation is a “witch hunt,” or that Trump has been investigated more often because of politics, Johnson said. Those who responded with “yes” could have been answering either question or both.

Monmouth University Polling Institute Director Patrick Murray made a similar point about the Suffolk University/USA Today survey question in a Twitter thread on March 18.

Another issue is that the question doesn’t offer a counter to Trump’s claim. “It only tells one side of the story,”Johnson said.



He said it would be better to ask respondents if they agree that the investigation is a “witch hunt,” as Trump claimed, or if they agree that possible collusion is something that “needs to be investigated thoroughly,” as others have claimed.

“It’s always the goal to be balanced,” he said.

Also, only asking “do you agree” can lead to acquiescence bias, which is when respondents are likely to agree regardless of the content of the question, Johnson explained.

“Some in our population will agree with any statement” that is presented to them, he said.

“Given the flaws mentioned,” Johnson said, “we’re not certain that this accurately reflects public opinion.”

Responding to the criticism, David Paleologos, director of the Suffolk University Political Research Center, told FactCheck.org in an email: “The statement links President Trump by name to his viewpoint on the investigation. If respondents were conflicted in any way, they opted for ‘undecided’ or ‘refused.'”

Similarly, Chrissy Terrell, director of communications and PR at Gannett, USA Today‘s parent company, emailed us a statement, saying: “USA TODAY and Suffolk University take seriously the framing of each question to ensure fairness and accuracy in response. We offer options that include ‘undecided’ or ‘refused’ for those who are unclear. Our reporting always specifies our methodology and with Suffolk University, we post the toplines and crosstabs to give transparency to the entirety of our polls.”
