Democratic Rep. Cynthia McKinney couldn't avoid a runoff in her first election following a scuffle with a Capitol Hill police officer, and now faces a second contest against her main challenger, Hank Johnson. In the Republican primary for lieutenant governor, former Christian Coalition leader Ralph Reed was unable to overcome his ties to disgraced lobbyist Jack Abramoff and conceded defeat to state Sen. Casey Cagle. In Georgia's Democratic primary for governor, Lt. Gov. Mark Taylor won 52 percent of the vote to defeat Secretary of State Cathy Cox, and will move on to face Republican Gov. Sonny Perdue in November. McKinney, the state's first black woman elected to Congress, is seeking her seventh term after a scuffle in March with an officer who stopped her when he didn't recognize her as she entered a House office building. A federal grand jury in Washington declined to indict the congresswoman, but she had to apologize on the floor of the House. Johnson, a former county commissioner, has roots in McKinney's core constituency. With 95 percent of precincts reporting, 1,540 votes separated the two. They face an Aug. 8 runoff, and the winner will face Republican nominee Catherine Davis in the heavily Democratic district. "The battle's engaged and I intend to win," said McKinney early Wednesday.
