Washington (CNN)A majority of American voters think Hillary Clinton's emails should be subject to a criminal investigation, a Monmouth University poll out Wednesday has found.
Poll: Most want criminal probe for Clinton emails
The numbers -- 52% of registered voters, including 82% of Republicans, 54% of independents and 23% of Democrats -- show that the Democratic presidential frontrunner's use of a personal email address on a private server during her tenure as secretary of state continues to be damaging.
They were asked: "Do you think Hillary Clinton's emails should be subject to a criminal investigation for potential release of classified material, or not?"
The survey was conducted July 21-Aug. 2, before Clinton's campaign announced it would turn over her server to the Justice Department in an effort to blunt an expanding probe.
Most voters, though, chalked Clinton's handling of her email up as a matter of convenience, with 51% saying that's why they think she used the private account and 38% said they believe she has something to hide.
Asked how much they'd seen or heard about Clinton's use of a personal email account, 61% said a lot, while just 24% said a little and 15% said nothing at all.
