As far as I know there were no allegations of child sexual abuse against Jacko, at least not while he was in office.   As is common with rural legislators, he joined the Republican Majority so he could actually do something for his constituents.   He was having or wanted to have a fling with some legislative staffer, not an uncommon thing, and went scratching on her door one night, not realizing that she was already in the rack with a reporter.   It made front page above the fold because he had committed the mortal sin of caucusing with the Majority.   If he had stayed with the Minority, nobody would have ever heard a word of it.   It cost him the office but I don't think it resulted in any criminal charges against him.
