Donal Blaney on 18DS has just reminded us that the LibDems are in power in Scotland and dozens of councils around the country and have never cut tax, despite the fact that they could. Good point ... so why should we trust them now?
Iain Dale also points to the fact that the LibDems have argued for higher taxes over the last 3 elections and have now switched. Have they accepted the political arguement for lower taxes? Dale once said that politics was like football - nobody switches from high tax to low tax like nobody switches from City to United.
The more I read about this, the more and more I feel we can't trust this LibDem plan.
