Jesse Jackson sure knows how to help a guy. He traveled to North Carolina last week to protest the role of Republican senator Lauch Faircloth in lifting power from Washington mayor Marion Barry and handing it to a presidentially appointed control board. "Faircloth essentially raped the democracy and disenfranchised every [District of Columbia] voter," Jackson harrumphed. "The mayor's office has been stripped." Faircloth responded that Jackson and Barry are welcome in North Carolina, but they'd be better off cleaning up D.C. Meanwhile, Faircloth's aides dispatched a crew to videotape the demonstration. Just imagine the TV ad next fall when Faircloth runs for reelection: Jesse Jackson, on camera, declaring Faircloth "too tough on Marion Barry." Couldn't buy better publicity than that.
