Palin to Launch East Coast Bus Tour

More signs of a presidential run: This weekend, Sarah Palin will begin an East Coast bus tour starting in Washington, the Huffington Post reports. “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,” says a rep. (Look for the bus with the Constitution on the side.) It all starts Sunday, when she joins DC’s “Rolling Thunder” motorcycle ride of mostly Vietnam vets.

A pair of former George W. Bush advance aides are organizing the trip, whose stops haven’t been announced yet. Meanwhile, Republicans are weighing in on her possible bid. “A Palin entry this summer will have less impact than it would have had if she entered a few months ago because her stock with rank and file Republicans has fallen this year,” says one strategist. “But she’d still shake things up,” he notes. “Everyone in the field would find themselves constantly being asked if they agree with what Palin just said.” Click to read about other signs pointing to a run.
