I find it particularly rich that people accuse the Lib Dems of gaming the system when they've merely responded to the rules of a game that they don't think any of us should be playing.
Yes, I've come to respect the Lib Dem enthusiasm for PR more and more, because they want it even though every time a more proportional election system has been introduced in local/devolved elections, it has led to the LDs doing worse than they usually do under FPTP.
