While Barack Obama and Hillary Clinton were sharing the stage in Unity, N.H., the Obama campaign announced yet another member of Clinton's former team will join Obama: Neera Tanden, Clinton's Senate legislative director and campaign policy director, is now Obama's campaign domestic policy director. In that role, Tanden might become involved in further developing Obama's plans for universal health care coverage. Clinton's plan called for mandating coverage; Obama has proposed mandating coverage for children, not adults, but under criticism from some experts who prefer Clinton's concept has acknowledged that if he becomes president there likely would be some tweaking of his proposal especially once Congress got involved.

Also announced today: Melody Barnes, executive vice president for the think tank Center for American Progress, becomes the Obama campaign's senior domestic policy advisor. Barnes, who is African-American, was chief counsel to Sen. Ted Kennedy, D-Mass., on the Senate Judiciary Committee from 1995 to 2003. Tanden also was at the Center for American Porgress as a senior vice president for domestic policy. Incidentally, the president and CEO of American Progress is John Podesta, who served as a chief of staff to President Bill Clinton.
