That's reaching to claim it was Trump like following if you're just basing it on Twitter. The election results would show that Andrews' appeal was far and wide. Much further and wider than the Twitter userbase.Andrews had twitter whipped into a frenzy with "fake news, Murdoch lies!" for every issue from COVID to Com Games to not managing Crown.
PR Guy was the tip of the spear and Twitter is an echo chamber of Andrews barrackers. Genuine rusted on cult members.
From what I remember of PR Guy, who was proven just to be joe public and not paid for by anyone, he started as a bit of a joke mimicking the News Corp style of clickbait negative headline they used to relentlessly attack Andrews, but in favour of Andrews.
