The civil standard is preponderance of evidence. The criminal standard is beyond reasonable doubt. I believe that the civil standard is appropriate for public elections. And for this type of proceeding, hearsay is admissible as evidence.
At this time, the prosecution in the court of public opinion has offered reams of eyewitness testimony (even as unreliable as that category of evidence may be), and the defense has offered "nuh-uh, wazzenme" and a parade of character witnesses--that are strangely reticent to back up their assertions with their specific reasons for believing that it would be out of character for Roy Moore to have pursued and sexually molested children when he was younger. As I am a cynical anarchist atheist, "he votes Republican and regularly attends Christian churches" actually holds negative weight for me.
There is also the other thing, the thing that is undeniable fact, and a matter of public record. He has twice been evicted--dragged kicking and screaming--from public office, for flouting the law. He has twice proven himself to be incapable of upholding the parts of the U.S. constitution that he doesn't like, and it would have only taken once for me to consider him unfit to be a U.S. senator.
And besides all that, he gives me the same vibe as an Alabama politician that I got from Rod Blagojevich as a Chicago politician. It's as though all the bacteria in my intestines are screaming in unison: "That guy is a colossal piece of isht, and we know isht better than anyone! Do not allow him within 100m of your government, your bank accounts, or your children!"
