It's official --Last Thursday, the FEC, at the request of Sen. Barack Obama, ruled that the 2008 presidential hopefuls can legally reserve the option of returning private donations in return for public funds upon winning their party's nomination. What began as an intriguing, eye brow-raising request has turned into a decision that may dramatically shape the fundraising race for the presidency. And even though this decision was made at the prompting of Sen. Obama, it will undoubtedly affect the fundraising choices of every one of the presidential candidates.
