Where do they go from here?

While Karin, Bill, and I will be leaving Denver for the Republican National Convention in St. Paul, Barack Obama and Joe Biden will be heading to Pennsylvania. The candidates and their wives will begin a four-day bus tour of battleground states in Beaver County. It's being called the "On the Road to Change" tour. They'll also be making stops in Ohio and Michigan. It will mark the first time Obama and Biden will campaign together as Democratic nominees.
