Who's funding TV ads by outside groups in Tennessee governor's race, and what do they want?

Outside groups in Tennessee's governor's race are spending millions to influence voters, with the Tennessee Freedom Fund supporting Marsha Blackburn and advocating for privatizing public schools through vouchers, while a dark-money group called the American Exceptionalism Institute is running ads attacking Blackburn without disclosing donors. The Tennessee Freedom Fund, linked to billionaire Jeff Yass and the Club for Growth, has spent $2.4 million, focusing on issues like immigration rather than school vouchers.
