A few Illinois Republican legislators desire to change the election law, to provide that Republican Central Committee members be elected by primary voters instead of by elected local party officials. Democrats, who control state government in Illinois, have jumped into the fray, and have attached the idea as as amendment to several election law bills. See this story from the Galesburg daily newspaper of March 30.
Ironically, as the article implies (near the bottom), the U.S. Supreme Court ruled unanimously in 1989 that such decisions are not the business of the legislature, but of the political parties themselves. The 1989 precedent was Eu v San Francisco County Central Committee.
