Wisconsin holds presidential primaries for the Democratic and Republican Parties. State party leaders decide who should be on their own party’s ballot. Wisconsin Democratic leaders were more inclusive this year than Wisconsin Republican leaders, as shown by the fact that Wisconsin Democrats included Mike Gravel, but Republicans did not include Alan Keyes.

The ballot will include these Democrats: Biden, Clinton, Dodd, Edwards, Gravel, Kucinich, Obama, Richardson. It will include these Republicans: Giuliani, Huckabee, Hunter, McCain, Paul, Romney, Tancredo, and Thompson.
