Sarah Palin’s bus tour will resume this weekend when she stops at the Iowa State Fair, she announced in an email Wednesday. “The heartland is the perfect territory for more of the One Nation Tour as we put forth efforts to revitalize the fundamental restoration of America by highlighting our nation’s heart, history and founding principles,” the former Alaska governor wrote in an email. Palin had not been expected to stop back in Iowa until Labor Day weekend, when she’s scheduled to address a Tea Party gathering at Waukee. She gave no more details about where her bus tour will stop after this weekend.
