We care a lot

Mildly interesting debate going on over at Lib Dem Voice about whether, in the event of a hung parliament, they should throw their lot in with the party which gets the highest share of the popular vote or the party which wins the highest number of seats. This might be a slightly radical concept for the party to grasp, but here's a suggestion. How about looking at the policy platform of the two main parties and see which party has policies you can broadly support? Or which one has policies to which you absolutely and violently object? Stop wittering on about the political process, and make a decision on principle for a change.
