It's quite ironic to think that the one policy the Lib Dems do all agree about - Proportional Representation; is the one policy guaranteed to fracture their party.
The Lib Dems alliance stretches from disaffected Tories to their grass roots who think they are left of Labour.
Bring on Proportional Representation like Labour promised in their manifesto and watch the Lib Dems disintegrate and all hope of a Tory victory evaporate. Come on Gordon, it's common sense. Trust the people, the majority will always want progressive policies. PR will benefit Labour here like it has in New Zealand.
