Florida ? The last of U.S. Rep. Katherine Harris’ key staffers appear ready to abandon her campaign for the U.S. Senate in a wave of resignations expected to start this weekend.

Harris, who is running against Democratic Sen. Bill Nelson, is likely to lose her chief political strategist, her campaign manager, her spokeswoman, her director of field operations and even a traveling aide who helps hand out stickers at campaign appearances.

Her campaign has been in disarray for months. She has struggled to raise money and has little support from top Florida Republicans.
