In her speech, Ms Harman said many people who voted Lib Dem in May "believed that they were a progressive anti-Tory party".To Labour its not about politics or economics or anything else, its about being anti Tory that drives the Labour Party.
I had been vaguely aware that something wasn't quite right with Labour for a few years until I heard a Labour blogger on the much lamented House of Comments podcast say that to understand Labour you had to understand that the Labour Party is just a coalition of anti Tories, and that's when it all became clear. Just think back to all the Labour rhetoric you have heard, they never discuss real policies other than being in the framewaork of being anti Tory.
And as the phrase above shows the LibDem crime in Labour's eyes isn't anything to do with politics, its all about working with the Tories. The term progressive is nothing to do with with economics or taxation, its code for anti Tory.
What a way to run a political party, no ideology, just hatred. That's why they always fail, because they just won't accept that sometimes spending ever increasing amounts of money because the Tories say we should cut back a bit isn't the way to run a country.
Which is why I will never vote Labour as long as I have a hole in backside.
