WASHINGTON — Georgia’s newest senator, Johnny Isakson, was an active stock trader in 2004, dabbling in companies ranging from fast-food to clothing to oil, according to Senate finance records released Tuesday.

Isakson, whose past assets usually placed him among the wealthier members of Congress and the richest in Georgia’s delegation, appears likely to keep that distinction for 2004.

Topping his list of assets were two bank stocks, each worth between $1 million and $5 million. But the Republican congressman-turned-senator also listed major holdings in numerous famous corporations, such as $100,000 to $250,000 in Starbucks, Bank of America, American Express and Gannett, and $50,000 to $100,000 in Liz Claiborne, MBNA America, Home Depot, and Citigroup.

Besides stocks, Isakson reported several real estate listings, including 12 acres in Rabun County, worth between $1 million and $5 million. He also has properties worth as much as $250,000 in Atlanta and Smyrna, as well as property in Hilton Head, S.C.

Georgia’s senior senator, Republican Saxby Chambliss, reported far fewer assets. His top ones were stock in Southwest Georgia Financial Group, worth $15,000 to $50,000, as well as a credit union account and subdivision partnership in Moultrie, both worth between $1,000 and $15,000
