A mandate for change.
Our sister party in England and Wales just elected their leader, and duly chose the magnificent Caroline Lucas MEP. She's smart, passionate, engaging, radical, and absolutely the right choice. If I were a member and if I had as many votes as Jack McConnell apparently does up here, I'd have voted for her seven times.
Looking around the internet for responses, Tom Harris regrets the diversification of British politics, Iain Dale is more charitable despite being a climate change denier "not [being] convinced by all the arguments on man made global warming", ASwaS backs Caroline to win in Brighton and urges the party up here to change, some Liberals are worried (rightly, I hope), and Jim Jay is naturally delighted.
Note: the update follows comment from Iain Dale below, and I'd be pleased to read any thoughts on the distinction he's describing. I'd also welcome Iain filling me in on the specific arguments he isn't convinced by.
