This map shows the composition of the Wisconsin State Senate as of March 1, 2011. The Senate consists of 33 senators who are elected to four year terms from districts around the state. Each senate district encompasses exactly three state assembly districts. Currently there are 19 Republicans and 14 Democrats.
Regular state senate elections are held in odd-numbered districts during gubernatorial election years (2006, 2010, 2014, etc.), and in even-numbered districts during presidential election years (2008, 2012, 2016, etc).
Each district of the map is shaded according to its representative's political party by default. You can use the controls above the map to display more detailed election data instead. See Instructions.
You can find very detailed maps of Wisconsin State Senate districts from the Wisconsin Legislature website. To find out who represents you, enter your address at the legislature's Who Are My Legislators? page.
