How much did it cost the GOP to have a fundraiser with LeeAnn Rimes?

Answer: 80K.

And how much did they raise? About 85K. 

"The money that the PAC raised hardly covered the cost of the event — it took in $85,000. The San Manuel Band of Mission Indians donated $50,000 to the committee, and the Morongo Band of Mission Indians Native donated $25,000. Blue Shield of California’s PAC chipped in $5,000 and the American Association of Clinical Urologists and a Tennessee-based donor gave $2,500 each."
