Mercer "Merce" Reynolds III (born June 17, 1945) is an American businessman. He was the finance chair of U.S. President George W. Bush's presidential campaign.
Reynolds, born in Chattanooga, Tennessee, earned a bachelor's degree in business administration from the University of North Carolina at Chapel Hill, and an M.B.A. from the University of Tennessee at Chattanooga. After serving briefly in the United States Army (1968–1969), he worked for Coca-Cola for ten years.
In 1979, Reynolds and business partner William DeWitt founded the investment firm Reynolds, DeWitt & Co.; he was its co-chair until 2001. Reynolds' other business ventures included Spectrum 7, an oil company which he co-chaired from 1980 to 1985 and which, in 1984 merged with the struggling firm Arbusto Energy, which was owned by George W. Bush. Reynolds was later an investor with Bush in the Texas Rangers baseball team. From 1985 to 2001, he was CEO of Reynolds Plantation, a golf community near Lake Oconee in Georgia.
Reynolds was Ohio finance chairman for George W. Bush's 2000 presidential and campaign, raising over $600,000 and was named to co-chair Bush's inaugural committee. From August 2001 to September 2003, Reynolds served as U.S. ambassador to Switzerland and Liechtenstein although he came under fire with criticisms for his lack of actual qualifications other than being a monetary contributor to George W. Bush's campaign. As the national finance chair of U.S. President George W. Bush's 2004 re-election campaign, Reynolds helped raise over $200 million for the successful effort and is sometimes credited with helping to deliver Ohio's key electoral votes to the President. He was a frequent guest of President Bush at the White House and at Camp David, and was a leading contender for the post of Commerce Secretary upon the 2004 resignation of Don Evans.
