The tactics of campaign leaflet delivery
On Thursday, a batch of official Yes to AV leaflets arrived by post at my home, what I assume must be part of the official free Royal Mail delivery to each voter to which each side in the AV referendum is entitled.
Half the leaflet was an application form for a postal vote.
It wasn't the most efficient use of resources, however - the same leaflet arrived three times over - one to me, another to my partner, and a third to our lodger.
The No campaign plan to use their free Royal Mail delivery rather differently. A detailed leaflet will go out shortly to the first named person at each address on the electoral register around the country.
Then, much nearer polling day, they'll put out a second, more general leaflet to the second named person at every address. That way most households will get two different No leaflets, delivered at public expense.
It follows the practice of many agents and candidates in Parliamentary elections these days, where they sometimes exploit the free mailing facility using assumptions that some people might see as rather sexist.
Given that the first person at most addresses is a man, some agents and candidates use the free mailing to send them a leaflet on issues they think are likely to concern men - the economy, defence and so on.
Then they put out a second leaflet to the second named person which stresses what they see as more feminine issues such as health and education.
And some calculate that the third and fourth people at an address are likely to be young people, so send them a third free mailing on issues of concern to young people.
