Folks should check out Jonathan Singer's interesting interview with John Kerry, which includes the newsworthy tidbit that McCain's staff members originally approached Kerry about the VP slot. I'm a bit unimpressed with the news (for reasons detailed here), but it's certainly a troublesome revelation for a campaign that really needed no help repelling conservatives.
On the subject of John McCain, I remain awed by how far his fortunes have fallen. It was barely a year-and-a-half ago that The Nation was running angry articles trying to remind Democrats and Independents that McCain was a conservative. Now it's The National Review trying to convince conservatives of the same. The Nation's article was trying to kneecap a threat to the left. The National Review's piece is trying to resuscitate McCain's relevance on the right. It's quite a shift.
