Protests in D.C. are a dime a dozen, but demonstrations for causes as compelling as stepping up to save the people of Darfur deserve what little pimping we can give them.

This Sunday the Save Darfur Coalition is taking to the National Mall, hoping to mass enough people to push President George W. Bush into taking more firm action to stop what has been referred to as a slow-moving genocide in the western Sudanese province of Darfur. The rally is part of the “Million Voices for Darfur” campaign, which seeks to send one million postcards to Bush advocating more aggressive action by UN and NATO forces.

The demonstration, which will take place between 3rd and 4th Streets in front of the U.S. Capitol, will feature a number of prominent speakers, from Senator Barack Obama (D-Ill.) to actor George Clooney and rap mogul Russell Simmons to Nobel Peace Prize Winner Elie Wiesel and Paul Rusesabagina of “Hotel Rwanda” fame.

Rally organizer Chuck Thies, a longtime D.C. political activist and friend of DCist, had this to say about Sunday’s rally:

People of conscience do not sit idly and watch from the sidelines while genocide is perpetrated against innocent civilians. Everyone can do something to raise awareness and demand action to protect the people of Darfur. Attend the rally, call your elected officials, send a Million Voices postcard to the President and Congress, involve your family, your neighbors, church, co-workers, community. We can stop this genocide and save hundreds of thousands of lives, but not unless we act.

People will start gathering at 1:30 p.m., with the program of speakers and music running from 2 to 4:30 p.m.
