President Bush is in Kennebunkport for what could be his last visit before leaving office. And protesters aren’t going to let it pass. A march organized by the Kennebunks Peace DepartmentSaturday coincides with a series of ":Hands Off Iran": demonstrations in dozens of cities. The anti-war group plans to march to a barricade near Walker’s Point, the waterfront home of Bush’s parents. For their part, the Bushes will be celebrating a wedding. A white tent has been set up on the Walker’s Point property for the reception for two White House staffers, one of them a distant Bush cousin.
