Labor’s former stranglehold on Bill Shorten’s home state of Victoria has reportedly crumbled in the last three months.

An analysis of Newspolls between October and December commissioned by The Australian found the opposition’s support has nosedived in Victoria from its strongest state when Tony Abbott was in power to its weakest under Malcolm Turnbull, who became PM in late September.

Labor’s primary vote in Victoria is now at 33 per cent, its second-lowest Newspoll result since 1996, The Australian reported.

Mr Shorten’s satisfaction rating in his home state reportedly plunged 14 points to 25 per cent compared to the same three-month period last year, which would be the lowest rating of any federal opposition leader in Victoria since 2003.

Nor is the damage restricted to The Garden State. Labor’s primary vote in Newspoll has reportedly fallen below 40 per cent in every state, and it trails in the two-party preferred metric in every state except South Australia.

The Australian‘s analyst predicted the result would tempt the PM to consider calling an early election.
