I hope IABU.
To be fair, this is only based on the West Country (I do quite a lot of driving so I'm including Cornwall, Devon, Somerset, Wiltshire, Dorset, bristol and bath). Driving around, I'd say the amount of stake boards and posters I've seen roughly represent these proportions:
Conservative: 60%
Green: 15%
UKIP: 15%
Lib dem: 8%
Labour: 2%
They have it sewn up, don't they? My mum is involved in politics and her prediction is a Tory/UKIP coalition 
If that happens I'm emigrating.
