I’ve just finished reading this, known by the title GameChange in the US. It’s a great, gossipy guilty pleasure that reads like a racy novel. But given the response to certain key episode (for example Harry Reid’s apology over his ‘no negro dialect’ comments) I think we can accept that it’s largely authentic. Apparently based on hundreds of anonymous sources it exposes the doubts, failures, flaws, strengths and successes of the candidates and their supporters. Best quotation, though, comes from McCain strategist Steve Schmidt: ‘Don’t politicise Oprah. She’s more powerful than you can comprehend. Like Obi-Wan Kenobi.’
