Card Resigns - First of Many?

As you likely know by now, Andy Card has resigned from his position as White House chief of staff; he'll be replaced by budget director Josh Bolten. Sources suggest the decision to leave was Card's, and that he was not forced out (although that story could certainly change). That Bush picked Bolten shouldn't come as a surprise, given that Bolten has long been in the White House inner circle. The question now arises whether this will be "the big shakeup," or if there is much more to come in the months ahead. I'm underwhelmed by this change, but it's at least a step in the right direction.
