Im still in shock at that graph. I guess if you really look at it, the Coalition's strategy was just woeful when you look at the details. The goal of an election is to win seats not just votes. Here is where they had no plan. They clearly gave up on the Teal seats, which would have required a fiscally conservative, socially moderate approach. Instead, it seems they decided to target the outer suburban seats. However, that is very difficult to do with their policy mix. For example, cutting Public Sector jobs and WFH. Most Public Servants live in the outer suburbs (NOT Canberra per se) and the people who most benefit from WFH are those in the outer suburbs. On top of that, the Coalition's Nuclear plan centred on building Nuclear plants in outer suburban areas and no one wants to live near one of those things.
I can already see the Sky News set (Credlin, Panahi and Bolt) saying you dont win elections by being Labor-lite, but this is just completely tone-deaf. The Abbott/Newman governments went full conservative and they were universally unpopular. Im not saying you need to move to the centre by any means, but you need to pick a strategy and ensure your policies target the right people. The Coalition campaign picked an audience but then decided on a campaign which isolated them and targeted a completely different audience. Madness. It was an awful campaign that clearly didnt resonate.
