Historically, Republicans have been strongest in the eastern and central portions of the state, while Democrats have been strongest in the northwestern part of the state. Occasionally, certain counties in the southern part of the state will vote Democratic. Marion County, Indiana's most populated county, supported the Republican candidates from 1968 to 2000, before backing the Democrats in the 2004, 2008, and 2012  elections. Indiana's second most populated county, Lake County, is a strong supporter of the Democratic party that has not voted for a Republican since 1972. In 2005, the Bay Area Center for Voting Research rated the most liberal and conservative cities in the United States on voting statistics in the 2004 presidential election, based on 237 cities with populations of more than 100,000. Five Indiana cities were mentioned in the study. On the liberal side, Gary was ranked second and South Bend came in at 83. Regarding conservative cities, Fort Wayne was 44th, Evansville was 60th and Indianapolis was 82nd on the list.
