Accountability Now formally launched today. The concept is for some big progressive organizations and top bloggers – people like Jane Hamsher, Markos Moulitsas, Glenn Greenwald, Nate Silver, MoveOn, SEIU, and Color of Change – to put together the resources and energies to primary bad, conservative Democrats. To me there is really nothing more exciting happening in the Democratic Party today than the prospect of having more democracy and challenging incumbents who fail to represent their district and the party.

Sam Stein of Huffington Post has the best article on Accountability Now so far.
