The new campaign manager is Maggie Williams, a longtime aide of Clinton's who served as the former first lady's chief of staff when Bill Clinton was president. Williams is a Hillary Clinton loyalist, not one of the "white boys" -- James Carville, Paul Begala and circle -- who some thought would move into leadership roles. This is very much inside=Hillary's-circle shift, rather than a power-play by Bill and his buddies.
But it is still a significant development. And this should be seen more as the beginning rather than the end of upheaval within the Clinton headquarters.
Job one, key Clinton backers admit, is a radical rethink of the candidate's "ask." The campaign needs to come up with a clear reason for Democrats to choose Clinton over Obama -- something better than "experience," which is losing badly to "change" in most exit polls of primary- and caucus-state voters. And, with tough primaries coming up in Maryland, Virginia and Wisconsin, she needs it fast.
