Richard Jackson called an 11:45 a.m. news conference yesterday to announce that he is a candidate for mayor of Washington.

No one showed up.

Undaunted, Jackson tried again. This time he scheduled the news conference for 3:11 p.m. He called local newspapers, television stations and radio stations.

Again, no one showed up.

"The key to this campaign is going to be the support I get from the people," Jackson said when reached at home late yesterday afternoon. "I have $111 to put into my campaign. I'm going to need contributions from the people."

Jackson is 40. He lives at 4416 Third St. NW and describes himself as a "self-employed graphic designer, illustrator and sign painter."

His first news conference was scheduled for the Tandoor Restaurant, 3316 M St. NW.The reason: "I painted their sign outside the door."

The second news conference was to be at the Uni-Camera shop at 1219 Wisconsin Ave. NW. "I painted their sign too," Jackson said.

Jackson also said that he called the second conference for 3:11 p.m. because, "It's a good time, a very good time. I like odd numbers. That's why I like 3:11 p.m."

Jackson said he was born in Los Angeles and came to Washington in 1961 after serving in the Marine Corps. He worked "at numerous places" during the 1960s before discovering he had artistic talent "around 1970." He has supported himself doing graphics and painting signs since then.

Jackson said there are two issues that most concern him in the election. "I'm very worried about the housing situation in Washington," he said. "We've lost our sense of community by relocating people and destroying their homes.

"I would also like very much to see a lottery in Washington," he added. "I think it's the one thing that could rejuvenate our economy and give us a chance to rebuild this city."

Jackson said the main reason he is running is because "people are tired of the same old thing every election. It's been the same for 11 years now. The same men. The same issues. The same problems. I want to find out what the people here really want. This is a way to do it."

Jackson joins a field of four candidates who have filed candidate registration statements with the D.C. Office of Campaign Finance: Council member Marion Barry, Council Chairman Sterling Tucker, Charles S. (Trummie) Cain and John Ray.
