With only a few weeks to go until the Aug. 24 primary, Democratic attorney general candidate Sen. Dan Gelber, D-Miami Beach, unveiled a web video on Tuesday morning. Gelber is in a close race with Sen. Dave Aronberg, D-Greenacres, for the Democratic nomination. There are other signs that the Gelber campaign is prepared to make a sprint until the primary -- they will be holding a fund-raiser Tuesday night in Tallahassee.
