The tax returns - along with a a new financial disclosure form - show that Barnes has raked in millions of dollars since he was ousted from the governor's mansion in 2002. He and his wife Marie listed a net worth of $16.6 million. That's up from $12.6 million in 2001 just before he left office. His total income in 2009 was $5 million.
Barnes said Wednesday he won't apologize for being succesful and could bring the same level of prosperity to the state.
Barnes' Democratic opponent, Attorney General Thurbert Baker, on Wednesday outlined an economic development plan he said would create 25,000 biotech jobs in Georgia.
