The good folks over at Progressive Accountability have highlighted this bit of video, in which John McCain sums up his approach to negotiating with Iran thusly, "So, if they want to communicate with us and we want to communicate with them, fine. We all have blackberries. It's fine."
They juxtapose this video with a section of McCain's July 13 interview with the New York Times in which the candidate admits that he neither owns a BlackBerry nor uses email. No wonder McCain is so insistent on having preconditions for negotiating with Iran, since actually owning a BlackBerry is a vital precondition to communicating with one.
