Sarah Palin Motorcycle Ride Expected At Bus Tour Launch

Sarah Palin is expected to jump on the back of a motorcycle as she kicks off a bus tour on Sunday in the nation's capital, according to multiple outlets.

HuffPost's Jon Ward relays background on the event:

"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," said Tim Crawford, treasurer of Palin's fundraising group, SarahPAC, in a statement provided to The Huffington Post. "The tour will originate in Washington DC and will proceed north up the east coast. More information will follow."

Palin will kick things off Sunday by taking part in the "Rolling Thunder" motorcycle ride -- comprised mainly of U.S. veterans of the Vietnam War -- that begins at the Pentagon and concludes at the Vietnam Memorial on the National Mall.

Palin's bus tour is stirring buzz that the former Alaska governor may be laying the groundwork for a presidential campaign in 2012.

The AP reported last week:

A Gallup poll of Republicans, taken before Palin announced the bus tour, showed former Massachusetts Mitt Romney favored by 17 percent. Palin followed closely at 15 percent. Ron Paul had 10 percent, Newt Gingrich 9 percent, Herman Cain 8 percent, Tim Pawlenty 6 percent, and Michele Bachmann and Jon Huntsman 5 percent each.

Palin's political action committee released a web ad on Friday promoting the potential presidential candidate's bus tour.
