We’re following former Alaska governor Sarah Palin’s bus tour through the Northeast, a trip that has renewed speculation about her presidential ambitions.

Details on the tour are still hazy. The trip will include a stop on Friday in New Hampshire, a state Palin has not visited since 2008. She also plans to visit the Civil War battlefields at Gettysburg and Antietam and the Liberty Bell in Philadelphia.

Palin released a Web video promoting the trip, and she has been updating supporters after each stop on the Web site of her political action committee, SarahPAC.
