If Clinton also loses New Hampshire to Obama, Penn’s future with the campaign may well be in jeopardy, strategists say. But that may be wishful thinking on their part. For one thing, there is no obvious candidate to replace him. Hillary’s advisers and Bill’s have never gotten along — and she has been particularly suspicious of his team. “Who they both trust — that’s a very small group,” says one former Clinton aide. “She is going to be very, very resistant to all of the white boys coming back.”
Another problem is that some of those who might potentially be brought in have already been sidelined. Former White House Chief of Staff John Podesta, for instance, is running a 527 organization called the Fund for America and is forbidden by law to even consult with the campaign.
