The Tories have approximately 250,000 members (most of which are over 65 years old), they managed to receive 8.8 million votes in the 2005 general election.
Labour have around 200,000 members and received 9.6 million votes.
The Lib Dems have 70,000 members and received 6.0 million votes.
In terms of votes per member that works out as follows;
Tories 35,000 votes per member
Labour 48,000 votes per member
Lb Dem 86,000 votes per member
The Lib Dems pride themsleves on their democratic image but that is an awfully low number of members per vote. This tells me that the Lib Dem vote is clearly the 'softest' vote. In terms of tax and spend the Lib Dems have similar policies to Labour. There are a lot of people voting Lib Dem that clearly should be voting Labour. Labour has to win back these voters.
The Lib Dems are the dustbin for disaffected Labour and Tory voters, but the majority of their voters and members are clearly social liberals, as the popularity of Simon Hughes demonstrates. Now your party is finally going to make its mind up to move to the right under Ming or Mark Oaten, now is the time to join Labour.
Labour is going to reinvent itself under a new leader and having the sort of people who are currently joining the Greens and Lib Dems in their ranks could make a massive difference in influencing what direction the party takes on electoral reform. Now is the time to reclaim the Labour party.
To stay in the Lib Dems is just supporting your party in its right wing future and possible coalition with the Tories who will never support electoral reform. It's make your mind up time, are you Labour or Tory?
