Background

This particular contest has seen considerable back-and-forth in sentiment over the tracking period, with various candidates gaining and losing momentum. The by-election is set against a backdrop of national political tensions, with state and city governments reportedly pushing back against federal efforts to impose new voting rules linked to funding.
