This is a significant move by Palin as this is the next step to a potential run for the 2012 Republican nomination

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 symbolically significant venues 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.

Members of Palin’s immediate family are expected to join her on the trip, which will eventually take her through key early-voting states.

Coming on the heels of the revelation that Palin commissioned a documentary extolling her accomplishments as governor, which will premiere in Iowa next month, the impending nationwide voyage is yet another strong indicator that she is leaning toward jumping into the 2012 race.
