Greetings from Miami, where Sarah Palin has just finished a news conference. It wasn't much of one. She took four questions and spoke for a little under seven minutes, leaving everyone pretty amazed at the brevity of it all. She didn't say anything of great import, but appeared uninterested in talking about the McCain campaign. "You guys in the media are wanting to dissect the past," she said.
