You’re talking about a guy who lost a close election to an opponent who was sworn into the Senate weeks ago, but he still never conceded the race. Don’t ask me to explain what motivates this weirdo.
40 year old "he said, she said" accusations should have not been permitted to have an impact on the election. Rational people should have stated that if there was anything to these claims, they should have been adjudicated in court 40 years ago.
