Cynthia McKinney, former congresswoman from Georgia, is running for her old seat as the Green Party candidate. McKinney was defeated by Rep. Hank Johnson in 2006. McKinney filed paperwork with the FEC on April 2 declaring her intention to run.
From the Atlanta Journal-Constitution:
A lightning-rod political figure, McKinney, 55, was defeated in 2006 by Johnson after a much-publicized run-in with a U.S. Capitol police officer and her accusations that the Bush administration may have known beforehand about the 9/11 terrorist attacks.
In 2008 she won the Green Party nomination and ran for president. McKinney and running mate Rosa Clemente were on the ballot in 31 states, but not Georgia.
