Is this "IDF terrorists using Palestinian as human shield" or "IDF rushing wanted man for medical treatment" or both?

Tory campaigners and their media assistants will definitely have calculated that playing up the narrative of landslide benefits them:

• encourages (remaining) Tory voters to vote out of fear
• complacency among Labour voters will cause some to stay at home
• complacency among left/centre tactical will cause some to just vote green instead of whichever party maximises chance of removing Tories.

The landslide narrative is dangerous for Labour and it's certainly not being promulgated by their campaign.

Farage presumably sympathises with the milkshake throwers, who only did so because they'd been provoked.
