Charlie Black tells the Washington Post: “He’s in a position to make [the decision] on short notice if he wanted to.” That could be read as McCain has already made the decision, and now all that they need to figure out is when to time the announcement. According to the Post, there’s a push to announce the pick before the Olympics start on Aug. 8, because the Democratic Convention starts right after the Olympics, and the Republican Convention starts right after the Democratic Convention. But I disagree with that move. I think at this point, it’s best to hold out until the convention to announce the pick. Think of it. Obama will be speaking to 75,000 at a football stadium in Denver on Thursday Agust 28 — he’ll be coming out of the convention with a storm of publicity, and Republicans kick things off that following Monday (which is Labor Day). I think if McCain holds out on picking a nominee until then, it will generate more excitement and interest in a convention that risks being seen as a dull affair.
