Clinton and Obama, the party's top 2008 presidential contenders, will be in Selma, Ala., Sunday to observe the 42nd anniversary of a civil rights march that helped end racial segregation in the South. Obama is scheduled to deliver the day's keynote address at a Selma church that morning, with Sen. Clinton speaking at another church nearby.
But late Thursday, the Clinton campaign announced that the former president would join his wife in a symbolic march across the Edmund Pettus bridge, where civil rights workers were beaten by state troopers in 1965. Obama also will
participate in the march, along with civil rights activists and others.
