Update, noon: Terry McAuliffe, the leader of the HRC team, is already taking to the airwaves to declare that there is no shake-up in the makeup of the campaign staff. Yes, kids, the rumors are apparently stinging. And McAuliffe has got to be pretty mad at his friend Bill Clinton for taking the internal squabbles public.

Original, 11:02 a.m.: Various campaign insiders are leaking to press outlets that Bill Clinton is peeved big time that campaign leaders for Hillary Clinton have allowed Barack Obama to take so many potshots at his wife without receiving a similarly negative response.

Several staff members may be fired and replaced, Big Head DC hears, with the likes of James Carville — someone who definitely knows how to play dirty politics. And a close Bill pal still.

Although Carville’s wife, Mary Matalin, is actively advising Fred Thompson’s GOP presidential campaign, Carville has rarely been involved in political campaigns as a principal adviser to a candidate since Clinton’s 1992 presidential victory.
