I hink that people should be aware of which of those actions were responsible, and the falsehoods told to support them so that they don't get sucked into believing and supporting them all over again.
Yes, yes, MaizieD and my DH after voting Tory all his life has come to that conclusion. He even recently wrote to our MP to tell him so.
However, what I am saying is that all the negative harping on about past falsehoods etc is no longer necessary, it is in fact counterproductive. It starts to insult one's intelligence.
Discerning previous Tory voters have already moved on, but the real problem, as with DH, is going to be to get them to actually vote at all. Instead of the constant bashing of past Tory mistakes and alienating voters, don't other parties need to actually get them on side? It's the way people try to do this, and the tone that is used, that is important and currently wrong. (Not so much in RL but on threads like on GN). People need to be gently led, but not driven to vote for a party they would never have considered doing so in the past. Drop the negative approach, try the more upbeat positive stuff.
