Here is your link to the actual poll:
Directly from the poll:
“These findings have changed very little since Rasmussen Reports first asked this question two years ago.”
And here is the poll from two years ago:
“59% Think Hillary Likely To Have Broken The Law”
So, two years ago, no change in the poll. Basically, 60% of people believe Clinton broke the law. This has been what the public has believed for over two years. And yet, Clinton almost wins the presidency.
