I would do anything for voting reform, but I won't do that

Things which the lib dems are prepared to do in order to get a referendum on voting reform:

Raise VAT
Cut housing benefit and increase homelessness
Cap immigration
Sack hundreds of thousands of public sector workers
Support Michael Gove's ideological experiment with schools

Things which the lib dems are not prepared to do in order to get a referendum on voting reform:

Hold two separate votes, one on the Tory plans to gerrymander the constituency boundaries, and one on whether or not to have a referendum on voting reform
