MIAMI (AP) - Republican contributors to Gov. Charlie Crist's independent campaign for the U.S. Senate aren't giving up their quest for refunds.

The attorney for two GOP donors said Monday he will appeal a Naples judge's denial last week of class-action status in the case. The ruling means each contributor to the Crist campaign would have to seek a refund through individual court action.

Some Republicans contend Crist should return at least $7.5 million given to his Senate bid before he left the GOP and became an independent last spring. Crist's attorneys say donors have many reasons besides party affiliation to contribute money.

An appeals court in Tallahassee is being asked to prevent the Crist campaign from spending the money in question.
