Disqualify them from running for office? Probably not.
But should you vote for someone who has had like five people, completely unaffiliated with each other and with no material incentive to do so, come out and accuse them of rape and other horrifying stuff?
I wouldn't. Remember we're fielding people for a job here. If you owned a daycare and got five messages from different people claiming that one of your applicants diddles children, would you hire them or would you be like 'well I haven't seen it proved beyond a shadow of a doubt in a court of law'.
