The Liberal Democrats as far as third parties is concerned, is an odd grouping. Formed from the Liberal Party (which genuinely was a believer in less government) and the Social Democrats (a breakaway from Labour in its truly Marxist days - which means the 1980s!), it was at first a bridge between Thatcherism and the isolationist loony left of old Labour - with New Labour it has swung to the left. All very well, except that with Gordon Brown taking over, New Labour has swung a little back to the left- plus the Tories rejected Thatcherism now in favour of a green agenda.

The Liberal Democrats are hardly liberal, they subscribe to the intolerant environmental politics as personified by Al Gore - the deliberate lies in order to get attention, the selective application of science, and preferring government intervention to achieve environmental goals, rather than getting government out of the way. They also want more government, like surrendering more powers and laws to Brussels. The Liberal Democrats are the new socialists- utopian dreamers whose best hope of getting power is local government (meddling petty fascism) or hoping neither Labour nor the Tories win an absolute majority - so they can form a coalition and blackmail Britain into electoral reform. There is a chance of that happening next time, although both major parties would much rather try to form a government and fail, than let electoral reform be foisted on them - unlike Jim Bolger

So now they are at around 11% in the polls, you have to ask "why bother". The only major policy they have different from the two major parties is their cut and run policy with Iraq - but besides that they have an old fashioned agenda of pouring tax money into the state sector, which continues to fail - and more taxes. The Independent is effectively the newspaper of the Lib Dems.

So they are a yawn, I am hoping that Labour voters might return to Labour and the Tories attract enough to squeeze the Lib Dems into a smaller party. They might find there is a part of the political spectrum ignored in the UK - it's called being Liberal!

Oh and Menzies Campbell (pronounced Mingus) has resigned... as they try to find their way. The problem is that it is appearing the Tories are a potential incoming government - the Lib Dems offer little new
