ATLANTA — In just over two weeks, voters will decide among crowded fields of Republicans and Democrats vying for Georgia's open U.S. Senate seat. To gain insights into the candidates' personal finances, The Associated Press requested access to the last 10 years of tax returns of each of the top candidates who are leading in fundraising and polls ahead of the May 20 primary. Republicans Karen Handel, Phil Gingrey and David Perdue each provided access to at least a portion of their tax returns.
