Most Democratic candidates are going where others tell them to for the next two days in some of the final cattle call candidate events of the year. The Democratic National Committee, meeting in Vienna, Virginia for the final time before their August convention, will hear from six of their candidates tomorrow.

On Saturday, candidates head to Des Moines for the Heartland Presidential Forum, held by Iowa Citizens for Community Improvement and other local groups. Organizers expect up to 5,000 attendees at the HyVee Hall in downtown Des Moines for the event.

Candidates are unlikely to make significant news at the events, but previous years' DNC meetings have helped, and any chance a candidate gets to address 5,000 Iowans is a huge opportunity. Plus, in Vienna, Democrats will have a chance to say hello to an important part of their 2008 strategy: One session is being keynoted by Colorado Gov. Bill Ritter, who will host the August convention and who Democrats hope can deliver his increasingly purple state to their party.

While candidates are out in Iowa, a DNC panel is expected to formally strip Michigan of its convention delegates when they meet early Saturday morning. Politics Nation, which is completely obsessed with the calendar crisis, will be there both days to bring you the news as it happens, even as it means waking up for an 8:30 meeting on a Saturday.
