Like most of my colleagues I've been developing something of an obsession with the US primaries, or at least the Democratic race.
I re-read Primary Colours last week, and have now started Barack Obama's "The Audacity of Hope". I thought it would be one of those books that everyone has on their bookshelves but no-one quite gets round to reading, but it's actually very good; just when you think it's getting a little repetitive he comes up with a way of putting something which actually really resonates.
Of course it was probably written with at least one eye on running for president, but he still comes across as genuine and thoughtful.
Wisconsin polls close at 8pm their time tonight; we'll probably still be here for the exit polls.
