380: Norman McAllister
Norman McAllister was a Vermont state senator who was accused of soliciting sex from women who worked for him or rented from him. One of the women who accused him died before trial, one of the women lied about testimony unrelated to her allegation, so the case centered on one remaining woman. First he pled guilty in a plea deal, but a judge allowed him to withdraw his plea. He was found guilty of improper acts and acquitted on two charges. The jury acquitted him of coercing sex but found him guilty of arranging for her to have sex with someone else to pay her electric bill.
His conviction was reversed, so he got a new trial that ended in a mistrial thanks to a juror watching a news story about the trial. In his fourth round, he was acquitted and is listed in the Exonerations database.
