New polling has found the Nationals have lost 40 per cent of voter support.

The drop from 5 per cent to 3 per cent means weakened support for the government, cutting the Coalition’s primary support from 39 to 37 per cent.

The polling, conducted exclusively by Resolve Strategic for The Sydney Morning Herald and The Age, was conducted earlier this month while debate raged about climate policy as well as scrutiny on the vaccine rollout and a political storm over hidden donations to former attorney-general Christian Porter.

Today on Please Explain, chief political correspondent David Crowe joins Nathanael Cooper to go deeper into the numbers and what they mean.
