The first post-Reconstruction era Republican elected to Congress from Florida was <answer>William C. Cramer in 1954 from Pinellas County</answer> on the Gulf Coast, where demographic changes were underway. In this period, African Americans were still disenfranchised by the state's constitution and discriminatory practices; in the 19th century they had made up most of the Republican Party. Cramer built a different Republican Party in Florida, attracting local white conservatives and transplants from northern and midwestern states. In 1966 Claude R. Kirk, Jr. was elected as the first post-Reconstruction Republican governor, in an upset election. In 1968 Edward J. Gurney, also a white conservative, was elected as the state's first post-reconstruction Republican US Senator. In 1970 Democrats took the governorship and the open US Senate seat, and maintained dominance for years.
