Sometimes DU bewilderes me

62. A different kind of open primary

In Wisconsin every primary ballot lists all the parties with their own candidates on different parts of the same ballot. For example, first the section named Republican Party with all their candidates listed and a line that shows the end. Then the section for Democrats, then Green Party, etc. (Whether Republican or Democratic goes first depends on who won the last general election. Other parties are ordered by lot.) Each voter can vote in only one section. If you vote on election day for more than one party, the tabulation machine will spit the ballot back and you can get another ballot to do it right. Absentee ballots (including those at early voting) are not counted until election day at city hall and any that are double marked are void.

This system would not help the party identify supporters, but on the other hand it preserves the privacy of the voter from revealing their preference in front of someone who might cause them trouble.
