The Economist/YouGov polls are the most detailed and interesting polls I’ve seen covering the US presidential race (it will be interesting to see whether YouGov’s strong prediction record in the UK holds true Stateside). The latest one (PDF) shows John Kerry leading George Bush 47% to 44%, despite the Swift Boar Liars’ best efforts – but it’s down from a seven point lead last week.

Somewhat strangely, Mr Kerry’s rating has only fallen by one point, while Mr Bush has gained three points. I can’t think of anything worthwhile he’s done in the last week to warrant this; then again, I can’t think of anything worthwhile he’s done in the last 50 years, so perhaps a reason isn’t necessary.

Amusing minor detail: 1% of people who say they’re Republicans say they’ll vote for Ralph Nader; less than 0.5% of people who say they’re Democrats will do the same. Hopefully the Republican activists who are lobbying to get Mr Nader on the ballot in swing states will be royally hoist by their own petards…
