Crickets on this story from the progressives who love to decry what they term “big money in politics.”

Duke Energy won’t be repaid the $10 million line of credit it guaranteed for Charlotte to host last year’s Democratic National Convention, the company confirmed Thursday.

As the credit line came due, Duke made official what it had signaled to shareholders in an earnings report last November. Because Duke can claim the money as a business expense for tax purposes, shareholders will foot $6 million of the cost.
