In 62 BC Julius Caeser's wife, Pompeia, hosted a sacred festival which no man was permitted to attend. However a young patrician managed to gain admittance disguised as a woman, apparently for the purpose of seducing Pompeia. He was caught and prosecuted for sacrilege. Caesar gave no evidence against Clodius at his trial, and he was acquitted. Nevertheless, Caesar divorced Pompeia, saying that "my wife ought not even to be under suspicion."
Anyone who alleges election fraud can be expected to be vilified with every venom that could be employed. So it helps to remain above even suspicion.
