Speculation over Palin's ambition

As the US Republican embarks on nationwide tour, many think she may run for the presidency.


    Sarah Palin, the high-profile Republican, has started a tour of US states on the back of a Harley Davidson motorcycle.

    The Tea Party favourite joined bikers in Washington DC to commemorate US war veterans.

    And as Al Jazeera's John Terrett reports, it has also fuelled speculation about a Republican presidential bid.
