MSNBC offers this report, which begins: “With so much attention on Obama’s reversal on public financing, liberal bloggers like Arianna Huffington and Josh Marshall have wondered why McCain’s own apparent flip flop on the subject hasn’t received as much scrutiny. Well, the Democratic National Committee is trying to change that by filing a lawsuit in US District Court in DC to force the Federal Election Commission to investigate McCain’s decision to opt in the public matching funds system for the primaries, secure a loan based on those public funds, and then withdraw from the system after becoming the GOP front-runner. McCain, though, never actually received those public funds before opting out.”
