Unless you are talking about some-other obscure protest, she made protest at Martha's Vineyard the same time Obama was there, but it was not protesting him.
It was instead an attempt to bring her positions some attention and possibly influence Obama's actions.
"There are several things that we wish to accomplish with this protest on Martha's Vineyard," Sheehan said in a statement:
First of all, no good social or economic change will come about with the continuation or escalation of the wars in Iraq, Afghanistan and Pakistan. We simply can't afford to continue this tragically expensive foreign policy.Cindy Sheehan heads to the Vineyard; wants anti-war demonstrators to emulate health-care protesters; will anyone cover the story? | Washington Examiner
Secondly, we as a movement need to continue calling for an immediate end to the occupations even when there is a Democrat in the Oval Office. There is still no Noble Cause no matter how we examine the policies.
Thirdly, the body bags aren't taking a vacation and as the U.S.-led violence surges in Afghanistan and Pakistan, so are the needless deaths on every side.
And, finally, if the right-wing can force the government to drop any kind of public option or government supported health care, then we need to exert the same kind of pressure to force a speedy end to the occupations.
