At a full staff meeting of the DNC, executive director Tom McMahon introduced his successor, Jennifer O'Malley Dillon, who walked staff members through what they can expect in the next month, according to a person present at the meeting.
The staff will be asked to resign by the end of February, but will have the chance to say if they’d like to remain on board. It's the same transition process that's been undertaken at the DNC after every political changeover since 1992.
O'Malley Dillon was received "warmly," according to the meeting attendee, and she welcomed input from staff as the new leadership figures out the new party structure.
She was joined at the meeting by two other Obama campaign veterans - Mitch Stewart and Jeremy Bird - who are expected to have leadership roles at the party under the new White House.
Virginia Gov. Tim Kaine took over as chairman yesterday, replacing Howard Dean - a sainted figure among the DNC's rank-and-file. Some party members are concerned that the popular 50-state strategy will be re-tooled under Kaine, but O'Malley Dillon promised Thursday that the program is here to stay.
