Illinois Governor Pat Quinn has asked the legislature to change the Illinois primary system from the type of open primary in which the voter (on primary day) must publicly ask for one particular party’s primary ballot, to the type of open primary in which the voter would decide which party’s primary ballot to use in the secrecy of the voting booth. See this story.
It would be better to switch to a true Open Primary, like that used in Washington, California, and Louisiana. This eliminates the need for party prequalification, and simplifies candidate qualification, and preserves the secret ballot.
