Campaign[]
Campbell, who was elected in 1992 as a Democrat, switched parties after the 1994 Republican Revolution. He faced a primary challenger, but won with over 70% of the vote. In the general election, Democratic nominee Dottie Lamm criticized Campbell of flip flopping from being a moderate liberal to moderate conservative.[2][3] In fact, throughout the entire campaign, Lamm mostly sent out negative attack advertisements about Campbell.[4]
