Three byelections will be fought in New South Wales tomorrow, with the “unpredictables” -- they are called “deplorables” in the US -- about to determine the results.

The main action is concentrated on Orange, a west-of-the-divide rural seat, and Wollongong, the former steel and coal city on the South Coast.

The third contest is in Canterbury, a Labor stronghold previously held by Linda Burney, now a federal MP. This Sydney seat is likely to stay in the ALP fold. But who can tell for certain these days?
