It doesn't really mean anything though, and I don't mean that anti-Labour either as it still would be meaningless if the Conservatives were polling 45%. In our first past the post system you could gain a majority on a much smaller figure, it's all about where those votes are and you could poll a huge slice without winning any seats at all.
The Lib Dems idea of yesteryear for proportional representation was ideal. It would likely mean more hung parliaments, but every vote counts wherever you are then. As a Brexit supporter, there is no way I'd vote for them as it could put the local Labour MP back in power, but I'm sure some will and we'll be stuck with a remain MP in W&L again. I have no choice but to vote Conservative to achieve what I want and that's disappointing.
