This. I voted Lib Dem and am a bit fed up with the crowing being directed at people who did. I'm not thrilled with the result, but I remain ok with the fact that I did not vote for Labour or the Conservatives, two parties I do not currently support. I voted Lib Dem because I wanted to register a vote for change. I voted positively, with hope, rather than with an "anyone but the Tories even if it means voting for a party I don't like" attitude.
And now I think the best possible outcome is that the Tories try for a minority government without the Libs Dems, fuck it up, and within a year we get a Lab/Lib coalition that includes electoral reform.
