One Nation leader Pauline Hanson plans to win another seat in a state by-election, backing in a former cocaine user despite the party cracking down on crime. A coach and fitness manager, Mr Herdegen vows to be tough on crime, aligning with the views of WA One Nation leader Ross Caddies. "That's a story I put out there to try and help inspire people to live happier and healthier lives," Mr Herdegen said on Tuesday. "I deactivated my social media to protect my family from people like (journalists)." "We used a system which checks everything - adverse media, email screening, phone screening, banned or disqualified persons' screening, court screening."
