Jacqui Lambie is very much *not* leftist; she's an Australian independent politician. Very extreme views, but in many ways a scatter-pack of hard left and hard right.
For example, in October 2016 she called for preemptively pardoning anyone accused of war crimes against the Taliban or the Islamic State, arguing that they should be excluded from the rules of war due to their "vile, disgusting culture and ideology". In January 2017, she enthusiastically endorsed Trump's restrictions on immigration and said that Australia should not only follow his lead, but double down and summarily deport anyone who "supported" Sharia law or was on a terror watch list, or "at least" charge them with treason for their opinions.
If she's any one thing, it's, "Enthusiastically authoritarian."
