Every time I vote there is always someone outside the polling station collecting the little number from the font of people's voting cards.
Invariably he or she wears a blue rosette though I suppose that doesn't make a difference, just that they are making it clear who they are in support of.
Is it some sort of market research? ie the code tells them which households are actually bothering to vote, so they target their doorstepping/leafleting to voters or abstainers?
Incidentally mrs Julian's recent chat with our kids in which she demonised people with blue ribbons, which I fear may have scared off the conservative doorsteppers the other week (see my old thread) has worn off completely. -When we encountered just such a be-ribboned man this morning, my children engaged him in a lengthly conversation about our cat, and how she can talk like a cartoon character. 😕
