In a move designed to propel her closer to a presidential run, former Alaska Gov. Sarah Palin will set out on a bus tour of the country on Sunday, making stops at symbolic sites along the way.

“Starting this weekend, 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 in a statement to RealClearPolitics. “The tour will originate in Washington, D.C. It will proceed north up the east coast.”

Details were still being hammered out on Thursday, but sources indicated to RCP that the bus tour is expected to last several weeks and will be divided into separate geographical stretches for logistical reasons.
