After logging a disappointing fundraising haul in the first quarter, Sen. John McCain (R-Ariz.) has decided to make a change at the top of his campaign's finance operation.

Carla Eudy, a longtime fundraising consultant for McCain, has been moved out of her role as finance director and will be replaced by Mary Kate Johnson. Eudy will remain with the campaign in a senior advisory role, according to communications director Brian Jones, who called Eudy "incredibly hard working."

"This is a continuation of the campaign restructuring that began earlier this month," Jones said.

That restructuring comes after a first quarter in which McCain raised $12.5 million and ended the period with just over $5 million on hand. Both figures placed him third in the chase for campaign cash, behind former Gov. Mitt Romney (R-Mass.) and former New York City Mayor Rudy Giuliani.
