Palin's bus tour keeps itinerary secret, baffles media and supporters

Sarah Palin's national bus tour kicks off today at "Rolling Thunder", a biker rally in Washington, DC, but where it will go tomorrow is anyone's guess. "Rolling Thunder" representatives have gone on the record saying that Palin was not asked to speak at the rally and as of this morning, no one in the organization seemed to know what her role in the event would be.

The rally begins at the Pentagon and proceeds to the Vietnam Memorial and is intended to raise awareness of American POW's and soldiers missing in action.

Palin's organization has declined to publish a list of dates for the bus tour, even to supporters. Vague plans have been floated of touring Civil War battle sites and locations like the home of the Liberty Bell in Philadelphia, then "up through New England". However the Chairman of the Connecticut Republican Party, Chris Healy says he has "heard nothing on this, nor have I been contacted" about a visit from the former Vice Presidential candidate.

Similarly, the New Hampshire Republican Party heard that Palin was coming to their state by watching the news. The details of where she will stop and what she will do when she gets there remain a mystery to anyone outside of the half-term Alaska governor's inner circle.

The tour is widely believed to be a chance for Palin and her staff to feel out the level of national support for a possible 2012 run. According to the New York Times, the release of "Undefeated", a documentary film Palin commissioned about her time as Alaska governor, as well as her purchase of a house in Arizona and the kickoff of the bus tour are all signs that increasingly point to the likelihood of a Palin candidacy.
