mikey is right, but only up to a point. when times are better, voters tend to stick to the middle ground, and at the moment, extreme politicos are irrelevant. however, whilst their meaage won't change, when times are hard there are more voters prepared to listen to the message of the extremist; it's so easy for the accusations of blame to be believed in those circumstances. we ignore the warnings from history at our peril.
"Labours vote stood up very well last Thursday, but its not difficult to see where the increased TORY votes came from is it ! "
That was the problem Mikey. Labour's vote stood up OK in most places in England and Wales but it needed to do better.
Labour lost there by the look of it for the same reason Ed Balls lost in Yorkshire: the LibDems did not vote Labour: in Morley they more or less all defected to UKIP and in the Gower enough went blue to see the Tories over the line.
What would depress me if I was a LibDem would be the reflection on how many votes for the LibDems in a lot of places seemed just to be a protest against the Big Two: and when their reputation nosedived it was UKIP who benefitted. Not very Liberal at all really.
