Looks like she might be in after all. Sarah Palin will launch a multiweek, nationwide tour of historical sites this weekend, hot on the heels of a new two-hour documentary about the former Alaska governor. “Sarah Palin will embark on a ‘One Nation' tour of historical sites that were key to the formation, survival, and growth of the United States of America," SarahPAC treasurer Tim Crawford said. The tour will start in Washington, D.C., at a motorcycle rally. The route and schedule have not been decided, but Palin will be accompanied by family members.
