The new Newspoll estimates Labor leading 56-44 (an effective 1.6% swing from the last election after accounting for the Liberals not contesting Richmond in 2018) off primary votes of Labor 41 Coalition 36 Greens 13 others 10. These results are not wildly different to the 2018 election, with Labor down 1.9%, the Greens up 2.3% and the Coalition up negligibly. For all the hype from some on the right about how hated he supposedly is, Daniel Andrews polls a rather strong +13 net rating (54-41) with the artist now known as Matt Guy on a not so flashy -17 (32-49). A modest Better Premier lead for Andrews given the other scores and the way preferred leader scores skew to incumbents (51-34) does provide some support for the idea that Andrews is a polarising figure and the minority who dislike him tend to do so strongly.
Seat Model
What might this poll look like if realised on election day? By uniform swing Labor would drop four of its 58 notional seats to the Liberals and Northcote (just) to the Greens, coming out just two down on its 2018 election result, but the uniform swing model is if anything potentially unkind to Labor's chances vs the Liberals in the 2PP seats. There are two major reasons for this: firstly, personal vote effects from the 2018 massacre will make it hard for the Liberals to pick off Labor marginals, and secondly the Liberals have a lot of ultramarginals that are at risk from random variation unless they can get a more substantial swing. They have nine seats on 1.5% or less (including occupied notional Labor seats) to Labor's four.
