Yeah the honesty, especially when it is about their position towards each other, is really quite striking and makes you realise how low most of our discourse has sunk.
You might be right re. reach but Stevenson's got a much much bigger online presence than the Green Party (something like 1.5M compared to 20K subs on YT and about x5 on IG and tiktok) so I assume Polanski is looking to leverage that and accelerate progress. They'll still be an element of preaching to the choir but hopefully they'll begin to make a dent.
Will be interesting to see how much traction the Let's Make Hope Normal Again video/campaign can achieve.
