Proportional representation Watch
At every election, they cause tactical voting and people can portray the 'two horse/three horse' race that is to be heeded when voting.
Think how much more democracy would thrive free of this paradigm.
The argument that you don't get a local representative for opinion doesn't stack up, because we won't get a national representative for local opinion either.
What you do still get is a local representative that has been selected, maybe not in such exact accordance with the local vote, but then the national sense of proportional representation, thriving democracy, and more possibilities for both change and responsiveness to people- the influence of who is governing being more responsive to national debates and the overall vote far outweighs this local representative question as a consideration, especially as political classes have in the past become so interchangeable and cynical anyway.
First past the post is regressive and supportive of oligarchies and stagnancy, and PR is way more progressive and conducive to thriving democracy.
It is not an accident FPTP is most loved by Tories.
