This is opinion. So read it as such. But consider it please.
Obviously if you read this based on the title. I assume you oppose the Tories.
But if you are wondering why labour are so keen to manage expectations. There is a reason.
Campaign funding wise the Tories are estimated to be 19m ahead of labour. But honestly at the moment they are not spending a huge amount more.
We know the Tories are skilled at election manipulation. So there is genuine fear that the Tories plan to launch a campaign within the last few days.
I.E. when there is less time and funding to ensure fact checking is effective.
They know Starmer is more publicity aware then Corbyn was. He is able to play it in a way that dose not scare traditional Conservative voters.
They also know thanks to Boris, that the courts are unable to punish them for outright lies during any political campaign. And that Rishi is prepared to lie about and accuse civil servants of lying when challenged.
As huge as polling is against the Tories. All it would take is some dramatic claim against the party or Starmer. To convince Tory traditional voters to bite their tongue and vote Tory. While convincing left wing voters not to vote or to switch to 3rd party in seats where labour are the 1st or 2nd party.
The fact we know they have a huge amount of money unspent. Makes it clear they plan to launch something nearer the end of the election. And the only advantage of leaving it so late. Is it will limit the ability of the party to effectively react. Or fact checkers to be able to prove and distribute evidence of lies.
Please be prepared for this.
Why do you feel the need to keep insisting that stupidity can cause bad writing when nobody is actually arguing otherwise? What everyone is saying is "bad writing does not imply stupidity". Those two statements are separate things.
