Essential Estrogen

Sen. Hillary Clinton's campaign is reporting JoDee Winterhof, who had been serving as Iowa campaign director, will move into a senior strategist role. The state director spot will be filled by longtime Vilsack supporter and staffer Teresa Vilmain.

Winterhof will become a primary surrogate in Iowa and will continue outreach efforts with women and other constituency groups. Vilmain will be responsible for day-to-day operations of the campaign in Iowa.

Vilmain has worked on the campaigns of many Iowans including Tom Vilsack, Tom Harkin and John Culver. She worked the (Bill) Clinton 1992 and 1996 campaigns as well as the 2000 Gore attempt. She worked on Vilsack's team earlier this year. Her national roles have included stints at the Democratic National Committee and EMILY's List.

The last line of the press release indicates Clinton plans to return to Iowa this weekend. No specific details, however, have been released.
