Problem is, Duncan isn't the only idiot in the Green ranks - Kitcat, Hawtree, Ms Kitcat ( apparently we're inbreds ), Bowden, Davey, Deane, MacCafferty - all have made absolutely stupid comments over the lifetime of this council. Either directly via twitter / social media or during council...
And as if by magic yet again a local Green shows why you'd need to be a bit dumb to vote for them locally - http://www.theargus.co.uk/news/11309015.Councillor_slammed_for__hired_killers__Armed_Forces_Day_tweet/
Agree with you about Lucas though.
And yet the Greens got an MP with considerably less than 20% of the vote. I suspect UKIP will get a very small number of seats - probably in Essex and the South West.
