Then-FBI Director James Comey criticized Clinton's server use in 2016, but he declined to recommend criminal charges.

Respondents were more divided on whether the remainder of Clinton's emails should be released to the public.

The poll found that just over half of likely voters, 54 percent, believe the emails should be made public. Thirty-two percent said they should be kept under wraps, while 14 percent were undecided.

The FBI recently refused an open records request for the FBI's files on the Clinton email investigation, saying that privacy interests outweighed the potential public interest benefits from releasing the files.

The strongest divisions occurred among party lines, with 77 percent of Republicans supporting the release of the emails, while just 34 percent of Democrats said they should be made public.

Clinton has long maintained that the FBI investigation into her email server helped cost her the 2016 presidential election. In May, Clinton blamed the letter sent by Comey reopening the investigation days before the election as the deciding factor.

“I was on the way to winning until the combination of Jim Comey’s letter on October 28 and Russian WikiLeaks raised doubts in the minds of people who were inclined to vote for me, but got scared off,” Clinton said in May.

Rasmussen Reports contacted 1,000 likely voters on August 31 and September 3, 2017. The margin of sampling error is +/- 3 percentage points.
