Quite, if there not prepared to be part of the debate, you're not part of the debate. I think it's fair the lib dems get a say though, as it was the Tories who forced them out.
Not only do they avoid the debate, but try to stifle the democratic process not allowing parties that they don't like...
The main loser tonight was the spineless tory Cameron who isn't prepared to have his and his parties opinions/policies scrutinised, that should tell you everything. There should have been an empty platform IMO.
Farage scored a massive own goal, other than that I thought they all made...
