I count 306 seats where Labour are 1st and the Conservatives 2nd, or Conservatives 1st and Labour 2nd.
In the other 326 seats, either the Lib Dems, Reform, Greens, SNP, Plaid Cymru or independents are a top two party. Where most voters live, the traditional Labour vs Conservative debate is no longer the relevant one.
Such people would just be less likely to vote at all if the process itself is disenfranchising. Plus it’s not just a question of understanding but of wilful ignorance or even malice.
The process needs to be simple enough for everyone, and it needs to be emphasised how such a voting system will help them be better represented.
I would like to think a PR system would lead to more of a focus on individual policies and less voting along tribal lines, but if you’re disenfranchised that’s not going to help anything. If we ever get a proportional system it needs to come with a very good educational campaign.
