Having had a day to think about this, I find myself conflicted regarding this poll.
While I absolutely believe Clinton should be charged, convicted, and disqualified from running for ANY public office for mishandling classified information , I'm less inclined to demand Comey's resignation.
Here's why: Think about his statements. He laid out what basically amounts to a cut and dried case against Clinton. He took great pains to list each and every instance where she had abused the the regulations regarding the handling of classified materials. He then proceeded to inform us that if it were anyone else, or should someone try this in the future, they would indeed face prosecution. The break occurred when he discussed what the DOJ would do, or wouldn't do, to be more accurate. He basically informed us that the DOJ wouldn't press charges against Clinton, regardless of the evidence presented and the fact that anyone else WOULD be prosecuted.
Granted, he should have recommended indictment, but in doing so he would've committed professional suicide. Knowing how those that go up against the Clinton's tend to have "accidents" it may have been a more personal worry.
I think he was doing what he could to let us know that the "fix" was in, and that his hands were being tied due to orders from above.
