Chris Lopez, communications director for the Denver 2008 Convention Host Committee, spoke with me two days ago about preparations for the Democratic National Convention August 25-28 in Denver.  He's got a big job, coordinating an expected 15,000 or so journalists who will cover what he calls the Superbowl of Politics.  Our conversation provided an intriguing look inside the massive effort going on here in Denver to get ready for an historic event.
