We continue our look at Wisconsin’s Congressional districts, this week with the fourth. The district contains the city of Milwaukee and includes suburbs along the shore of Lake Michigan. The fourth district is Wisconsin’s most urban, with a population density more than 15 times that of any other district. As an urban center, the fourth employs higher rates of occupations such as health care and law than the rest of the state. The district has both the lowest median household income and the highest income disparity in the state. Milwaukee is also home to two of Wisconsin’s Division I universities, Marquette and UW-Milwaukee. Democrats have long held the seat in Congress since the 1950s. The current incumbent is Gwen Moore, who has held the seat since 2005. She faces two challengers, Republican Tim Rogers and independent Robert Raymond.
