If Tom Vilsack should become his party's nominee for president in 2008, he and his wife may avoid the cookie controversy that surrounded the Clintons back in 1992. ... This was the quote from HRC: "I supposed I could have stayed home and baked cookies and had teas, but what I decided to do was to fulfill my profession which I entered before my husband was in public life." While Christie Vilsack was a teacher for years, she cooked, too. Mrs. Vilsack intends to bring her "cheesy corn casserole" to the potluck in Mount Pleasant tomorrow night that's meant as a sort of kick-off for Vilsack's presiential campaign. Jeff Link, communications director for the Vilsack presidential campaign, says Mrs. Vilsack won a blue ribbon at the Iowa State Fair when she entered this recipe in the casserole competition.
