Well, Iain Dale was right- the by-election in Ealing has been extremely dirty.
Quite frankly though- the dirt has very largely come from one side. The Conservatives have been so desperate to chalk up a success that the have stooped to some very low tactics indeed. The mysterious "leaking" of the postal vote last night- apart from being illegal- was part of a consistent pattern- false postings being made on Lib Dem sites coming from the computers of the Conservative campaign itself, and even the naked opportunism of the Tory candidate, so recent a convert from Labour.
Whatever "David Cameron's Conservatives" do tomorrow, I hope never to see such an unprincipled and unscrupulous campaign ever again.
