I can only assume John Reid feels really, really strongly about AV to risk the inevitable opprobrium from some quarters for sharing a platform with David Cameron.
In common with a lot of people, I cannot claim to feel that much fire in my belly either way, but I have to say the nature of the No campaign is leading me towards a Yes vote.
It says something for how personality driven our politics has become that so much of the coverage has focused on the implications for Cameron, fighting for a No vote, and for Nick Clegg, who is campaigning for Yes.
Of the three main party leaders, Ed Miliband strikes me as the only one who has actually made arguments that speak to the issue. Cameron has ventilated a milder version of the crazy scare stories peddled by the No campaign, whilst Clegg sees it as a lifeline to what remains of his credibility.
It would not be unhelpful to Labour for Clegg to lose on this, but Ed has decided the issue is more important than the narrow political interest, and is to be commended for so doing.
Compare and contrast the role of The Sun newspaper in Scotland, backing the SNP in the upcoming elections, because Cameron would rather have Alex Salmond as first minister, rather than Labour leader Iain Gray.
As I said when I blogged on this a while back, as the signs of support for the SNP were all around, the paper nationally is passionately pro Union. But that principle wears quickly thin.
I remain unconvinced their backing will help the SNP that much. I should also tell John Reid that I spoke last night to two people who said they had switched from No and Don’t know to Yes on AV on the back of his event with DC. I acknowledge that both are Rangers fans. Democracy works in odd ways.
