Keep in mind, nobody thought Moore would win, even Trump who backed the other guy (until the other guy lost and then Trump pretended he didnt by deleting his tweets of support).
The evidence is pretty damning. And you are playing the "what about" game by referencing those democrats, but so far I have not seen any accusations that they molested children.
Moore is playing this exactly how Trump did during the election when he was accused by multiple (adult) women. Deny, then threaten to sue. But as a lawyer friend told me, people who threaten to sue are usually guilty. If they weren't, they would just sue. The problem with suing is that you also open yourself up to questioning. Moore wants no part of that. The women accusers have offered to testify in front of a senate committee as long as Moore is also called to testify. McConnell declined, stating that Moore was not a Senator yet.
