Will One Nation be the new Greens?

The transformative rise in support for One Nation over the past six months – at least if polls are to be believed – faces its first real test in Saturday’s South Australian state election.

When the results are announced starting at 6 p.m., they will be dominated by questions that, to an unusual extent, resonate beyond state borders.

Will there be anything left of the Liberals in Adelaide?

Skeptics may point out that pre-election polls have often been inconclusive on One Nation, most recently the party’s underperformance in last year’s federal election.
