than in rural ones. Iowa's industrial areas were not concentrated in one town, but spread out among the state's 15 largest cities. Along with industry developing across the state, Democratic strongholds developed in such urban areas. This demographic change translated into Democratic success first in Iowa's largest city Des Moines. There Democrats identified and registered thousands of new supporters. In 1954 Democrats "won control of the Polk County Board of Supervisors, every county administrative seat, and [...] all of Polk County's state legislative seats. Taking advantage of internal Republican strife and backing from organized labor, Democrat Herschel Loveless won an upset victory against incumbent Republican Governor Leo Hoegh in the 1956 election. Two years later Loveless won reelection and Democrats would capture 50 State House seats, 12 State Senate seats, and 4 Congressional seats. In 1960 Iowa's government was dominated by Republican control. However, during the 1960s and 1970s Iowa Democrats used their success in Polk County as a model in organizing Democratic supporters that was repeated across Iowa. While Democrats were defeated in runs for several offices in 1966 and 1968, following social disruption related to opposition to the Vietnam War and cultural changes, Governor Harold Hughes won three terms in office. Democrats rebounded in the 1970s, in part due to the sophisticated approaches of Democratic candidates John C. Culver and Richard C. Clark. They used computer models to analyze voters on a precinct-by-precinct basis, and ran issue-driven campaigns attuned to local issues. Each was elected to the U.S. Senate, in 1972 and 1974, respectively. Republicans regained dominance in the late 1970s in state government, but Democrats remained a competitive party in Iowa. Presidential level Democratic presidential candidates were historically unsuccessful in capturing the state's electoral votes. The Republican Party's presidential nominee captured Iowa's electoral votes from 1856 to 1908, when the Republican Party dominated most of the Northern Tier of states. Southern Democrat Woodrow Wilson won Iowa in the 1912 presidential election against Republican incumbent William Howard Taft. It was twenty years before another Democrat, Franklin D. Roosevelt, won the state, and that during the Great Depression and a time of national crisis. With the exception of President Lyndon B. Johnson's landslide election win in the 1964 presidential election, the Democratic nominee for president did not win Iowa's electoral votes from 1952 to 1984. Since the 1988 presidential election, Democrats have had more success in capturing Iowa's electoral
