And yet Obama has already spent more than every GOP candidate combined.

(Politico) — Sen. John Kerry (D-Mass.) has lent his name to a fundraising solicitation that raises the specter of millionaires and billionaires funding an outside effort against President Obama.

“When I was the Democratic nominee for president in one of the closest and toughest elections in history, a group of billionaires did something unprecedented,” Kerry wrote. “They wrote million-dollar checks to fund lies about my service on what were called “Swift Boats” in Vietnam — and in so doing, they turned the boats my crewmates and I served on into a new political shorthand for the most vicious smears imaginable: ‘swiftboating.'”

In 2004, an anti-Kerry 527 group formed to raise questions about his war record and air ads against the senator, then running as the Democratic nominee for president. Its’ spokesman, Jerome Corsi, would go on to become one of the leading proponents of the ‘birther’ conspiracy that falsely suggests Obama was born in Kenya or elsewhere.

Kerry points to a $3 million dollar donation to a pro-Romney super PAC by Houston construction magnate Bob Perry as the next round in an outside effort against Obama.

“One man. Three million dollars. And that’s just the start,” Kerry writes.
