The last paragraph just about sums it all up.
The choice is Labour’s, to go on trying to secure narrow, shallow and occasional FPTP victories on policies only acceptable to those who want nothing to change, especially on climate, or mobilise and build the progressive majority that exists in our country. Infrequent, weak single party government or strong progressive alliances most of the time? The flick of a switch in terms of how we count votes is a game changer for progressives and the planet.
I don’t want a system that relies on the least worst option. This system is low hanging fruit for abusive regimes with a war chest to spend on campaigns.
I think you can even position it as a continuation 0f the ideas that a lot of people’s Brexit vote was based on. Parliamentary sovereignty requiring it to actually be representative of the population’s opinion. A higher quality parliament for a parliament with greater responsibilities.
