But as a big a nut he is on guns and other matters, he will certainly be out-nutted in the Senate by the Queensland no.2 Senator for Pauline Hanson, Malcolm Roberts. An ageing engineer (a professional which produces some of the most obnoxious examples of Dunning-Kruger), he's the climate change denier whose mutterings about international banking family conspiracies made even Andrew Bolt distance himself from his group. I see from the link that he's also (naturally) an Agenda 21 conspiracist completely opposed to any support of renewables (even though, as Abbott found out, quite a lot of people who might be dumb enough to vote for Hanson actually quite like their solar panels on the roof). I bet he's a goldbug, too. And, I wouldn't be surprised if he loves his guns as much as Leyonhjelm.
So, it's going to be interesting, and worrying, to watch what crap he will come out during Senate speeches.
